Given the following diagram, find the required measures.

The three inside angles of a triangle need to equal 180 degrees.

You are given angle 1 as 36 degrees, so the other two angles need to equal 180-36 = 144 degrees.

You are told that angle O equals angle P, so since they are both the same, divide the remaining degrees by 2:

Angle o = 144 / 2 = 72
