Question

If two supplementary angles are in the ratio 1: 2. Find the measure of the bigger angle? ​

Answer 1

Step-by-step explanation:

Answer

Option (A) is correct.

Two supplementary angles are in the ratio 1:2

So, let two angles be x and 2x

Given that, angles are supplementary

∴x+2x=180

o

⇒3x=180

⇒x=

3

180

o

⇒x=60

o

Therefore, bigger angle is 2x=120
