Answer to Question #321 in Geometry for farad

Question

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

Answer 1

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.
