Question #321

One of the adjacent angles is two times larger than the other. Find these angles.

Expert's answer

Let one angle be equal to xº. So the other angle is equal to 2xº. The angles are adjacent, so their sum is 180º. We can write the equation:

X+2x=180

3x=180

X=60

So, the angles are equal to 60º and 120º.

X+2x=180

3x=180

X=60

So, the angles are equal to 60º and 120º.
