Step-by-step explanation:
A = B
7x + 40° = 3x + 112°
7x - 3x = 112° - 40°
4x = 72°
x = 18°
A = 7x + 40°
= 7(18°) + 40°
= 126° + 40°
= 166°

Answer:
9.5 trust me
Step-by-step explanation:
sin 32 = x / 18
x = 9.5
It would be 30 degrees since a line is 180. You subtract 150 from 180 and get 30.
10 to the second power=100
74.75/100= .7475
