Two ribbons are laid across each other in a craft class, crossing at a single point. At the crossing, one angle is 3 times another adjacent angle that lies on the same straight ribbon. Find the smaller of these two angles.

Question

Accepted Answer

45. Let the smaller angle = x. They form a linear pair: x + 3x = 180, 4x = 180, x = 45°.
