Question

Given that the measure of 2x is 45°, and the measure of zy is 499, find the
measure of z

Answer 1

86 degrees

Explanation:

The angles of a triangle all add up to 180.

x is 45 degrees

y is 49 degrees

49 + 45 = 94

180 - 94 = 86

The last angle of the triangle is 86 degrees. Since z is on the opposite side of it, it is equal to 86
