Question:
An angle is equal to 8 times its complement. Determine its measure?
Solution:
It is given that required angle = 8 times its complement
Let 'x' be the measured angle
angle = 8 times complement
angle = 8 (90 - x)
x = 8(90 - x)
x = 720 - 8x
x + 8x = 720
9x = 720
x = 80
Therefore measured angle is 80.
