Question

Given that the measure of ?x is 60°, and the measure of ?y is 90°, find the measure of ?z

Answer 1

The measure of angle z is 30

Explanation:

The angles of a triangle all add up to 180. So we can set these measures equal to 180 and solve for the unknown.

60 + 90 + z = 180

150 + z = 180

z = 30
