I would say screw it and use the calculator anyway
Check the picture below.
make sure your calculator is in Degree mode.
Answer:
B
Step-by-step explanation:
1 : 2 = 1/2 : 2 = 1/4 : 2 = 1/8 : 2 = 1/16 : 2 = 1/32 : 2= 1/64
Those are supplementary,
(x+8) + (3x+2) = 180
4x + 10 = 180
4x = 170
x = 170/4 = 85/2 = 42.5 degrees
x+8 = 50.5 degrees
3x+2 = 129.5 degrees
I think I just answered this question yesterday
