Question

Za and Zb are
complementary angles. Za measures 59º.
What is the measure of Zb?

Answer 1

Complementary angles are two angles whose sum adds up to 90 degrees
Za + Zb = 90
You know Za measures 59
59 + Zb = 90

Solution: Zb is 31 degrees

Answer 2

Zb = 31

Explanation:

Complementary angles mean that the angles add up to 90 so:

Za + Zb = 90

59 + Zb = 90

Zb = 90 - 59

Zb = 31
