Question

the measure of supplementary angles are in the ratio 3 : 2 .find the value of each angle

Answer 1

Let the angles be 3x,2x

Two angles are said to be supplementary if their sum is equal to 180°

so,

3x+2x=180

5x=180

x=180/5

x=36°

Frist angle = 3x =3×36=108

Second angle=2×36=72°

Answer 2

$\large{\boxed{\bold{\green{Solution :\longrightarrow}}}}$

Let the first angle be 3x.

And second angle be 2x.

A/q,

3x + 2x = 180°

=> 5x = 180°

=> x = 180°/5

=> x = 36

•°• Required angles

First angle = 3x = 3×36° = 108°

Second angle = 2x = 2×36° = 72°
