Question

Two supplementary angle differ by 3O. Find angle

Answer 1

Answer:

Let the angle be x

Supplementary angle of x=180-x

Difference between angles=30

x-(180-x)=30

x-180+x=30

2x=210

x=105

Angle=105

Supplementary angle=180-105=75

Therefore,required angles are 75 and 105.

Answer 2

ANSWER:-

Given:

Two supplementary angle differ by 30°.

To find:

Find the angle.

Solution:

Let the angle measured be x°

Therefore,

It's supplementary angle will be (180°-x)

It is given that,

=) (180°- x )-x = 30°

=) 2x= 180° - 30°

=) 2x = 150°

=) x = 150°/2

=) x = 75°

Hence,

180° - x

=) 180° - 75°

=) 105°

Therefore,

Angles are 75° & 105°.
