Answer:
x = 12.75
Measure of angle YXZ = 49.75 degrees
Explanation:
Complementary angles have a sum of 90 degrees so we add them and set them equal to 90.
3x + 2 + 5x - 14 = 90
Combine like terms
8x - 12 = 90
Add 12 to both sides
8x = 102
Divide both sides by 8 to isolate x
x = 12.75
Measure of angle YXZ = 49.75 degrees
