Question

Angle TVZ makes a linear pair with angle ZVW so the measure of angle TVZ plus the measure of angle ZVW=180 degrees. Angle ZVW is also a linear pair with angle RVW. Angle RVW is a vertical angle to angle TVZ. Use these relationships to determine the measure of angle TVZ.

Answer 1

Explanation:

2x +15 +2x +5 = 180

4x = 180 - 20

x = 160/4

x = 40

TVZ + 2x +5 =180

TVX +2(40) = 180 -5

TVX = 175 - 80

TVX = 95
