Answer: 
</h3>
Explanation:
The identity we'll use is cos(-x) = cos(x) for any value of x.
So cos(-150) = cos(150).
Then locate the angle 150 on the unit circle. The terminal point is 
The x coordinate of this terminal point is the value of cos(150).
I have that and it says GK equals 36 and GI equals 16
Y+8=3y
-2y=-8
y=4
104*2=208
360-208=152
152/2=76
x=76°
