Given :

30 degree more than its complement

To Find :

find the measure of an angle which is 30 degree more than its complement

Solution:

Let the angle be x

Complement of angles: A pair of angles whose sum is 90°

So, complement of angle = 90-x

We are given that the measure of an angle which is 30 degree more than its complement

So, x-(90-x)=30

x-90+x=30

2x-90=30

2x=120

x=60

Hence The angle is 60°
