Answer:
This is the alternate exterior angle theorem
Step-by-step explanation:
This is because angle 2 and angle 7 are in the <u>outer</u> part of each side of opposite lines
<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- x = y
- 2(70 + 60) + x + y = 360
<u>Work:</u>
- 2(130) + x + x = 360
- => 260 + 2x = 360
- => 2x = 360 - 260
- => 2x = 100
- => x = 50
Hence, <u>the value of x is 50°.</u>
Hoped this helped.

Answer:
Step-by-step explanation:
One
Sin(x) = 15/24 = 0.625
x = sin-1(0.625)
x = 38.68
Two
Cos(x) = 8/11
Cos(x) = .727
x = cos-1(.727)
x = 43.34
Three
Tan(x) = 20/37
Tan(x) = 0.5405
x = tan-1(0.5405)
x = 28.39
Four
Cos(x) = 18/23
Cos(x) = .7826
x = cos-1(0.7826)
x = 38.50
Answer:
-9
Step-by-step explanation:
2x + 7 = -11
2x = -11 - 7
2x = -18
x = -9
First you subtract (1/4) from each side to get C by itself, then you convert (4/4) into 1. Then you divide both sides by (-4) to get C to equal 1. So your final answer is C=-1/4
