Question

The ration of two supplementary angles are 1:3 what is the measure of the smaller angle?​

Answer 1

Answer:

45°

Step-by-step explanation:

Let :-

• The ratio be 1x : 3x

We know :-

• The sum of supplementary angles is 180° .

On adding :-

→ x + 3x = 180°

→ 4x = 180°

→ x = 180°/4

→ x = 45°

Hence the smaller angle is 45° .
