Answer:
x = 6; ∠ONP = 24°
Step-by-step explanation:
1. Find the value of x


2. Find the measures of the angles
(a) x = 2
∠ ONP = x² - 2x = 2² - 2(2) = 4 - 4 = 0
This answer does not make sense because O lies in the interior of ∠MNP.
We disregard x = 2.
(b) x = 6
∠ ONP = x² - 2x = 6² - 2(6) = 36 - 12 = 24
When put in a calculator, the answer is 12.22 (recurring)
