Question

Find the angle which is four times it's complement​

Answer 1

Answer:

The complement of the angle x is given by (90 - x). Hence, the angle which is four times its complement is 72 degrees.

Answer 2

Answer:

Let the angle be ' x '

Then it's complement will be 4x

We know that sum if two angles is 90° degree.

Then the angles are said to be complementary

angle.

$4x + x = 90 \\ 5x = 90 \\ x = 90 \div 5 \\ x = 18$

Hence the angle is = 18

and it's complement will be ( 18×4 ) = 72
