Let's call the angle we're trying to find x.
The complement of x is 90-x.
The supplement of x is 180-x.
According to the problem, we have:
90-x = (1/8)(180-x)
To solve for x, let's first simplify the equation:
720 - 8x = 180 - x
Solving for x:
7x = 540
x = 77.14
So the angle we're looking for is x = 77.14 degrees.
To find the supplement, we subtract from 180:
180 - 77.14 = 102.86
Therefore, the answer is E) 102.86°.
