Question

Ch 6 9th class ncert
An angle is 5times of it complementary angle
Find angles

Answer 1

We know that completary angles sum is 90

Let the two complementary angles be x&y

The x+y=90

x=5y

Then 5y +y =90

6y=90

y =15

And x=5y=75

Answer 2

complementary angles =90°

angles =5x

=5*90

=450°
