Mathematics

If an angle is eight times its complementary angle, then the measurement of the angle is

$80^0$

SOLUTION

Two angles are said to be complimentary angles if their sum is $90^0$.

Let $x$ denote the required angle. Then its complimentary angle is $90-x$.

It is given that,

$x=8\times\left(90-x\right)$

$\implies \ x=720-8x$

$\implies 9x=720$

$\implies \ x=80^0$
