Question

An angel is 30⁰ less than twice its complement. Find the angels.​

Answer 1

Explanation:

We know that, complement angle is;

=) (90-x)°

A/q

Let the angle be x.

=) x= 2(90-x)°- 30

=) x= 180° - 2x -30

=) x+2x = 180 -30

=) 3x = 150

=) x= 150/3

=) x= 50°

Thus,

The angle is 50°.

Answer 2

Step-by-step explanation:

Let the compliment angle be 'a'

2a-30°=90°-a

2a+a=90°+30°

3a=120°

a=40°

therefore, the angles are 40° and 50°
