Question

3. The angles are supplementary and the smaller is one half of the larger.​

Answer 1

Answer:

Let the larger angle be x°

So, the smaller angle will be 1/2 of x° = x°/2

It is given that these two angles are supplementary. So

x° + x°/2 = 180°

[2x° + x°] /2 = 180

x° = 120

x°/2 = 120/2 = 60°

The angles are 120° and 60°
