Given the following diagram, find the missing measures.

Angle O and P are the same.
Subtract angle 1 from 180 and divide by 2:
Angle O = 180-36 /2
Angle O = 144 /2
Angle O = 72
Answer:
∠ O = 72°
Step-by-step explanation:
Since ∠ O = ∠ P and ∠ I = 36°
The sum of the 3 angles in a triangle = 180°, thus
∠ O = [tex]\frac{180-36}{2}[/tex] = [tex]\frac{144}{2}[/tex] = 72°
