Answer:
x= 50°
Step-by-step explanation:
the total angles in a triangle must equal 180 so just subtract 80 and 50 from 180
Answer:
x = 130°
Step-by-step:
I looked at the triangle with the angles 50° and 80°. to find the missing angle in that triangle, you want to add the numbers and then subtract 180° from that because when you add all three sides of a triangle, it equals 180°. So when you add 50° and 80°,you get 130°. Now you have to do 180° - 130° and you get 50°. Now that you have the missing angle for the last triangle, you can use that angle to find the measure for the line across from that. To do that, you have to take 180° and subtract 50°. You would get 130°. Your answer for x is 130°.

Trigonometric Ratios
The ratios of the sides of a right triangle are called trigonometric ratios. The longest side of a right triangle is called the hypotenuse and the other two sides are called the legs.
Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides as follows:
Cosine Ratio
[tex]\displaystyle \cos\theta=\frac{\text{adjacent leg}}{\text{hypotenuse}}[/tex]
Sine Ratio
[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]
Consider the angle of θ=30°, then we can write:
[tex]\displaystyle \cos 30^\circ=\frac{x}{12\sqrt{3}}[/tex]
Solving for x:
[tex]x=12\sqrt{3}\cos 30^\circ[/tex]
Since:
[tex]\cos 30^\circ=\frac{\sqrt{3}}{2}[/tex]
Then:
[tex]x=12\sqrt{3}\cdot \frac{\sqrt{3}}{2}[/tex]
[tex]x = 18[/tex]
Now apply the sine:
[tex]\displaystyle \sin 30^\circ=\frac{y}{12\sqrt{3}}[/tex]
Solving for y:
[tex]y=12\sqrt{3}\sin 30^\circ[/tex]
Since:
[tex]\sin 30^\circ=\frac{1}{2}[/tex]
Then:
[tex]y=12\sqrt{3}\cdot \frac{1}{2}[/tex]
[tex]y = 6\sqrt{3}[/tex]
Answer:
[tex]x = 18[/tex]
[tex]y = 6\sqrt{3}[/tex]

Write an equation of the line that passes through the given points.
(2,6) (-4,-2)
Answer:
y = 8/6x + 10/3
Step-by-step explanation:
You find the slope (m) first which is
Change of y over change of x
(6) - (-2) over (2)- (-4)
8/6 = m
Then you plug it into the equation y = mx + b
y = (8/6)x + b
Now you pick any of the set of points to plug in for x and y to solve for b
(6) = (8/6)(2) + b
6 = 8/3 + b
b = 10/3
Then plug into the equation for just m and b to get the equation of the line that passes thru both sets of points.
y = 8/6x + 10/3

Error Analysis A contractor purchases 7 dozen pairs of padded work gloves for $97.44. He
incorrectly calculates the unit price as $13.92 per pair for the expense report. What is the correct
unit price? What is the error?
The correct unit price is $
per pair
Answer:
Unit price = $1.16
His error was he divided $97.44 by 7 when in fact he should have divided 97.44 by 84
Step-by-step explanation:
7 dozen pairs
1 dozen = 12
7×12 = 84
97.44 ÷ 84 = 1.16

help im confused!! i need to find the x
please find the area of this irregular shape
Answer: 10 sq units
Step-by-step explanation:
Area of triangle: 1/2 x b x h
1/2 x 2 x 2 = 2
Area of the left triangle is 2 sq units
1/2 x 4 x 2 = 4
Area of the right triangle is 4 sq units
Area of square: l x w
2 x 2 = 4
Area of square is 4 sq units
Area of figure: A of square + A of r tri. + A of left tri.
4 + 4 + 2 = 10
The area of the figure is 10 sq units.

April wants to multiply 6 and 42 using the distributive property. Which of the following number sentences shows how
she could do it?
06x42 = 42 x6
06x(40+2) =(6x 40) + 2
O(6x42) x1=6x (42 ×1)
06x(40 +2) = (6x 4o) + (6
2)
Answer:
I'm pretty sure the answer is the last one;
6 x (40+2) = (6 x 40) + (6 x 2)
The 6 is distributed to the 40 and the 2

Mike created a cone that has a diameter of 8 feet and a height of 3 feet. Find the volume of this cone.
Answer:
V= 50.27
Step-by-step explanation:
V=(3.14)4^2(3/3)
50.27
The volume of the cone created by mike with diameter of 3 feet is 50.24 feet³
Volume of cone-based problem:What information do we have?
Diameter of cone = 8 feet
Height of cone = 3 feet
Radius of cone = 8 / 2
Radius of cone = 4 feet
Volume of cone = (1/3)(π)(r²)(h)
Volume of cone = (1/3)(3.14)(4²)(3)
Volume of cone = (1/3)(3.14)(16)(3)
Volume of cone = 50.24 feet³
