Question

Let m AngleA = 40°. If AngleB is a complement of AngleA, and AngleC is a supplement of AngleB, find these measures

Answer 1

mAngleB = 50 degrees

mAngleC = 130 degree

Explanation:

The way I did this was by subtracting the given "mAngleA = 40" from the angle that complementary angles are at: 90 degrees, which means that equals 50 degrees. Then, I did the same with mAngleC with the angle that supplementary angles are at: 180 degrees. 180 - 50 = 130 degrees.

Hope my explanation wasn't too hard to follow!
