Question

Two supplementary angles are in the ratio of 3:2. The value of two angles are: 
1. 60° & 30°

2. 108° & 72°

3. 60° & 120°

4. 36° & 54°​

Answer 1

Answer:

Given two supplementary angles are in the ratio 3:2.

Let the measurement of the angles be 3x and 2x.

Two angles are said to be supplementary if they sum upto 180

o

.

Then we have,

3x+2x=180

o

5x=180

o

or, x=36

o

.

So the smaller angle is 36

o

×2=72
