Answer:
A=35, B=55, and C=25
Step-by-step explanation:
Angle A and the angle next to it are linear pairs, so you can subtract 145 from 180.
if you already know Angle A, and that the other angle is 90 degress, you can add 90+35 and subtract it from 180 to get Angle B
Angle C is paired with the angle across from it (I forgot what the term is called) so it is 25 degrees.

Answer
The answer is negative 14.
Step-by-step explanation:
When you add a negative by a negative it equals a negative. Like if you add 1 + 1 it's going to equal 2 which is a positive, not a negative. So the answer is technically 8 + 6 which is 14 and all you have to do is add a negative sign.

Answer:
I think it is B
Step-by-step explanation:
=========================================================
Work Shown:
The smaller angles UVN and NVW add up to the largest angle UVW.
This is due to the angle addition postulate.
(angle UVN) + (angle NVW) = angle UVW
(6x+13) + (46) = 11+10x
6x + 59 = 11 + 10x
6x - 10x = 11 - 59
-4x = -48
x = -48/(-4)
x = 12
----------------
Extra info:
If you're curious about the angles, then we use that x value to find them
angle UVN = 6x+13 = 6*12+13 = 72+13 = 85 degreesangle NVW = 46 degreesangle UVW = 11+10x = 11+10*12 = 11 + 120 = 131 degreesNote how 85+46 = 131 to show that (angle UVN) + (angle NVW) = angle UVW is a true equation. This confirms our answer for x.

The diagram shows a 6 ft student standing near a tree. The shadow of the student and the shadow of the tree ends at point A. What is the height of the tree?
Answer: 18ft
Step-by-step explanation: I took the quiz and got 100%
The height of the tree is 8.3 ft.
To solve this problem, we have to find the angle of elevation from the student.
To do this, we have to assume or bring out a right angle triangle and solve for the.
Given that we have the distance of A to F and the point to F
A to F = 5ftE to F = 6angle ?Trigonometric RatioUsing trigonometric ratio,
We can find the tangent of this angle
[tex]tan\theta = \frac{opposite}{adjacent} \\tan\theta = \frac{6}{5}\\ tan \theta = 1.2\\\theta = tan^-^1(1.2)\\\theta = 50.2^0[/tex]
The angle of elevation can be calculated using sum of angles in a triangle is equal to 180 degrees
[tex]180 = 90 + 50.2 + x\\x = 180- 140.2\\x = 39.8^0[/tex]
Assuming a right angle triangle from the point the student is standing, the distance from him to the tree would be
[tex]15 - 5 = 10ft[/tex]
Let's use the tangent of the angle to find the height of the tree.
[tex]tan\theta = \frac{opposite}{adjacent} \\tan 39.8 = \frac{x}{10}\\x = 10 tan39.8\\x = 8.3ft[/tex]
From the calculations above, the height of the tree is 8.3 ft.

A triangle has sides with lengths of 4 yards, 10 yards, and 11 yards. Is it a right triangle?
yes
no
Answer:
no
Step-by-step explanation:
for a triangle to be a right triangle, the sum of the square of its legs must equal the square of its hypotenuse
a² + b² = c²
in this problem, 4² + 10² ≠ 11²
16 + 100 ≠ 121

Answer:
y=4/5x-18/5
Step-by-step explanation:
there are multiple ways we can find the slope, let's use two points and the point slope form y=mx+b for this equation. we can find the slope by using the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
in this case, we can use the two points (-3,-6), (2,-2)
y2=-2, y1=-6, x2=2, x1=-3
so, the equation is [tex]\frac{-2-(-6)}{2-(-3)}[/tex]
this reduces to 4/5
our slope is 4/5, so the equation for now is y=4/5x+b
let's use (2,-2) to find b. the y is -2, x is 2
-2=4/5(2)+b
-2=8/5+b, multiply both sides by 5:
-10=8+5b, subtract 8 from both sides
-18=5b, divide by 5
-18/5=b
our final equation is y=4/5x-18/5

What is the area of this triangle?
Answer:
The area of the triangle is 24 inches.
Step-by-step explanation:
First you multiply 8 by 6.
8 * 6 = 48
Next you divide by 2 because a triangle is half of a square.
48 ÷ 2 = 24
So, the answer is 24.

What are the coordinates of the point in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the ratio of 1 to 6?
Answer:
The coordinates of the point P in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the ratio of 1 to 6 will be:
(x, y) = (-1, -7)Step-by-step explanation:
Let P be the point.
As the point P is in the directed line segment from (-2,-8) to (5,-1) into the ratio of 1 to 6
i.e.
(x₁, y₁) = (-2,-8)
(x₂, y₂) = (5,-1)
Rise = y₂ - y₁ = -1 - (-8) = -1 + 8 = 7
Run = x₂ - x₁ = 5 - (-2) = 5 + 2 = 7
1 : 6 ratio means the point P lies at
[tex]\frac{1}{6+1}=\frac{1}{7}=14\%[/tex]
Thus,
rise for P = 7 × 14% = 1
run for P = 7 × 14% = 1
Thus, coordinates of P will be:
x = -2 + 1 = -1
y = -8 + 1 = -7
Thus,
The coordinates of the point P in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the ratio of 1 to 6 will be:
(x, y) = (-1, -7)
