Answer:
The supplement of the angle is 102.86°
Explanation:
Let
x-----> the measure of the angle
we know that
The complement of the angle is (90-x)°
The supplement of the angle is (180-x)°
so
(90-x)°=(1/8)(180-x)°
Solve for x
720°-8x=180°-x
8x-x=720°-180°
7x=540°
x=77.14°
Find the supplement of the angle
(180-77.14)°=102.86°
