volume_mute
- x =
- m(∠ZYQ) =
- m(∠PYQ) =
Correct Answer
(1) 10
(2) 55
(3) 125
Explanation
- To find x, use the vertical angles rule where ∠ZYQ and ∠XYP are vertical, then their measures are the same
- 2x + 35o = 6x - 5o
- 4x = 40o
- x = 10o
- Substitute x in the measure of angle ∠ZYQ,
- m(∠ZYQ)= 2x + 35o = 2 * 10o + 35o = 55
- ∠ZYQ and ∠PYQ are supplementary, then
- m(∠PYQ) = 180o - 55o = 125o
