Question

Two angles are complementary. mZT is (3x + 17)° and mZW is 19°
Solve for x and for mZT.

Answer 1

x = 18

mZT = 71º

Explanation:

Complementary angles total 90º

(3x + 17) + 19 = 90

Subtract 19 from both sides

3x + 17 = 71

mZT = 71º

Subtract 17 from both sides

3x = 54

Divide both sides by 3

x = 18
