Geometry 10 Angle measures

Question

An angle measures 140° more than the measure of a supplementary angle. What is the measure of each angle?

Answer 1

Hi Merinda,

Recall that a pair of supplementary angles sums to 180 degrees.

180-140=40

40/2=20

So the smaller angle is 20 degrees, and the larger angle is 140 degrees larger, or 160 degrees.
