Question

If two supplementary angles are in the ratio 1 : 2, then find the measure of bigger angle

Answer 1

Answer:

The answer is 120.

Step-by-step explanation:

Let the ratio be 1x and 2x

1x +2x = 180

3x = 180

x = 180/3

x = 60

The bigger angle measure is 60 × 2 = 120

Answer 2

Answer:

The measure of bigger angle is 120°

Step-by-step explanation:

Let, The ratio be x and 2x

x + 2x = 180° (Being the sum of supplementary angle)

Then,

x + 2x =180°

3x= 180°

x =180°÷3

x= 60°

therefore

2x= 2*60°

= 120°
