Answer 2

Step-by-step explanation:

As we know that the two angles are called supplementary angles if sum of those two angles be 180° .

In the given question, let two angles are x and 2x

Since, they are supplementary,

x+2x=180°

=> 3x= 180°

=> x=60°

2x=2*60° =120°

Therefore, the bigger angle is 120°.
