Assume that θ is an acute angle in a right triangle satisfying the given conditions. Evaluate the 5 remaining trigonometric functions. Sketch a triangle in the correct quadrant and label.
sec θ= 17/15
sin θ<0
Answer: See step by step. Replace the x with theta
Step-by-step explanation: Since sin is less than zero, and secant is positive. This means the trig values are in Quadrant 4.
We know that secФ=17/15. We need to find sin,cos,tan,csc, and cot.
We can find tangent by using the identity
[tex]tan^{2} (x)+ 1=sec^{2} (x)[/tex] where x is theta.
[tex]tan^{2} (x)+1=\frac{289}{225}[/tex]
[tex]tan^{2} (x)+\frac{225}{225} =\frac{289}{225}[/tex]
[tex]tan^{2}(x)=\frac{64}{225}[/tex]
tan x=[tex]\frac{8}{15}[/tex], Tangent in the fourth quadrant is negative so the answer is instead
[tex]tan x= -\frac{8}{15}[/tex]
We can find cotangent by taking the recipocial of tan so
[tex]cot=-\frac{15}{8}[/tex]
We can find cos by taking reciprocal of sec remeber that cosine is positive in 4th quadrant so the answer is
[tex]cos =\frac{15}{17}[/tex]
We can find sin by doing quoteint identies.
[tex]\frac{sin x}{cos x} =tan x[/tex]
[tex]\frac{ sin x}{15/17} =-\frac{8}{15}[/tex]
[tex]sin x= -\frac{8}{17}[/tex]
To find csc, take reciprocal of sine.
[tex]csc=\frac{-17}{8}[/tex]

you know that your line is perpendicular to the line with equation y equals 3x + 5 right whenever a line is perpendicular to another perpendicular not parallel to the line has a negative slope of the other line for example if you had a line with slope 2 x in the line perpendicular to that would have slope -1 / 2X so then you line in your question has slope -1 / 3 x by doing the Rococo of 3 and adding a negative sign to your equation sulfur looks like this y equals negative 1 / 3 x + B where is B is a constant 3 all you have to do is solve for b is a plug in the coordinate values 6 equals x minus -2 equals one in rearrange y equals -1 / 3 x + B negative two equals negative one over three 6 plus b negative two equals negative two plus be there for me easy roast F4U equation of the line is y equals -1 / 3 x

ABCD is an isosceles trapezoid.
measure of angle b=
measure of angle d=
measure of angle c=
Answer:
∡b = 53°
∡d = 127°
∡c = 127°
Step-by-step explanation:
in trapezoids, the two top angles are equal and the two bottom are equal
also, there are 360 degrees in any 4-sided polygon
53 + 53 + x + x = 360
2x + 106 = 360
2x = 254
x = 127
Answer:

Andre surveyed a random sample of 20 students and
found that 13 of them were in favor of having school
start one hour later. The school has 250 students. Make
an estimate, based on Andre's survey for the number of
students in the school who are in favor of having school
start one hour later.
O 65 students
O 87 students
163 students
170 students
Answer: 163 students
Step-by-step explanation:
First find the percentage of students who were in favor of having school start one hour later based on the sample of 20 students.
= 13/20 * 100%
= 65%
The apply this percentage to the total number of students in school to find your answer:
= 65% * 250 students
= 162.5
= 163 students
The number of students in the school who are in favor of having school start one hour later is; C: 163 students
What is the random sample?We are told that 13 out of the 20 surveyed students were in favour of having school start one hour later. Thus;
Probability = 13/20 * 100% = 65%
Now, the school has 250 students and as such, the number of students in the school who are in favor of having school start one hour later is;
65% * 250 students = 162.5 ≈ 163 students

The equation of the line A is 3x+2y=10.line B is parallel to line A and passes through the points (4,6).find the equation of the line B.
Answer: [tex]y=-\frac{3}{2}x+12[/tex]
Step-by-step explanation:
To find the equation of line B, we need to find the slope first, then the y-intercept. We first want to convert line A into slope-intercept form, so we can find the slope.
[tex]3x+2y=10[/tex] [subtract both sides by 3x]
[tex]2y=10-3x[/tex] [divide both sides by 2]
[tex]y=5-\frac{3}{2}x[/tex]
With the slope-intercept form of line A, we can see that the slope is [tex]-\frac{3}{2}[/tex]. We take the slope and the given point (4,6) to find the y-intercept of line B.
[tex]y=-\frac{3}{2}x+b[/tex] [plug in (4,6)]
[tex]6=-\frac{3}{2}(4)+b[/tex] [multiply]
[tex]6=-6+b[/tex] [add both sides by 6]
[tex]b=12[/tex]
With the y-intercept, we know the equation for line B is [tex]y=-\frac{3}{2}x+12[/tex].

A survey found that women's heights are normally distributed with mean 63.7 . And standard deviation 3.7 . The survey also found that men's heights are normally distributed with mean 67.5. And standard deviation 3.7. Consider an executive jet that seats six with a doorway height of 56.4. Complete parts (a) through (c) below.
Complete question :
A survey found that women's heights are normally distributed with mean 63.6 in and standard deviation 3.7 in. The survey also found that men's heights are normally distributed with mean 69.3 in and standard deviation 3.7 in. Consider an executive jet that seats six with a doorway height of 55.7 in.
1-What percentage of adult men can fit through the door without bending?
2-) Does the door design with a height of 56.35in. appear to be adequate? Why didn't the engineers design a larger door? Choose answer below
A. The door design is inadequate, because every person needs to be able to get into the aircraft without bending. There is no reason why this should not be implemented.
B. The door design is adequate, because the majority of people will be able to fit without bending. Thus, a larger door is not needed.
C. The door design is inadequate, but because the jet is relatively small and seats only six people, a much higher door would require major changes in the design and cost of the jet, making a larger height not practical.
D. The door design is adequate, because although many men will not be able to fit without bending, most women will be able to fit without bending. Thus, a larger door is not needed.
Answer:
A.) 0.135%
B.) C. The door design is inadequate, but because the jet is relatively small and seats only six people, a much higher door would require major changes in the design and cost of the jet, making a larger height not practical.
C.)
Step-by-step explanation:
Percentage of adult men that can fit the door without bending :
Obtain the Zscore :
Mean height of men, m = 67.5
Standard deviation, s = 3.7
Zscore = (x - m) / s ; where x = 56.4
Zscore = (56.4 - 67.5) / 3.7
Zscore = - 11.1 / 3.7
Zscore = - 3
P(Z < - 3) = 0.0013499 (Z probability calculator)
P(Z < - 3) = 0.0013499 * 100% = 0.13499%

Answer:
1- 10% of -80 is -8.
2- 28 is 4% of 700.
3- 25% of a number is equal to 1/4 or 0.25 of it.
4- 13% of a number is equal to 0.13 of it.
5- 15 is 12.5% of 120.
Step-by-step explanation:
1. 10% of ________- 8
2.28 is 4% of _________
3.25% of ________
4.13% of______
5.15 is 12.5% of _____
To determine the missing numbers in the statements, the following calculations must be performed:
1-
10 = -8
100 = X
100 x -8 / 10 = X
-800 / 10 = X
-80 = X
Therefore, 10% of -80 is -8.
two-
4 = 28
100 = X
100 x 28/4 = X
2800/4 = X
700 = X
Therefore, 28 is 4% of 700.
3-
25% of a number is equal to 1/4 or 0.25 of it.
4-
13% of a number is equal to 0.13 of it.
5-
12.5 = 15
100 = X
100 x 15 / 12.5 = X
1500 / 12.5 = X
120 = X
Therefore, 15 is 12.5% of 120.

Answer:
50ft
Step-by-step explanation:
Hi,
Considering that one side is equal to 38 degrees, we know this isn't a 30 - 60 - 90 triangle.
One of the legs is equal to 40 feet
So, tan(b) = 40/x
tan(38 degrees) is 0.78 round up to 0.8 (if that's what your teacher wants)
0.8 = 40/x
0.8x = 40
x = 50ft

The two angles with y in them need to add up to 180 degrees
10y + 3y + 11 = 180
Simplify:
13Y + 11 = 180
Subtract 11 from both sides
13y = 169
Divide both sides by 13
Y = 13
Now solve for those two angles:
10y = 10(13) = 130
3y + 11 = 3(13) + 11 = 50
The other two angles are the same as these.
The larger angles = 130
The smaller angles = 50
