Question

Let mZA = 40°. If zB is a complement of ZA, and ZC is a supplement of ZB, find these measures.

Answer 1

Angle b= 50

Angle c= 130

Complementary angles are two angles that add to equal 90

Supplementary angles are two angles that add to equal 180

To find the measurement of angle b, subtract 40 from 90 (50)

To find the measurement of angle c, subtract 50 from 180 (130)
