Answer:
The answer if 79
Explanation:
The measure of angle 2 has a supplementary side. That means that we need to subtract. 180-137=43. Now we add that with angle P to get 101. Now that we have the sum of two sides in the triangle, we subtract from the whole which is 180 degrees all together. 180-101= 79. 79 degrees is the missing part to the triangle. Hope this helped :)
