It is given in the question that
If four angles of a convex pentagon measure 120°, 93°, 108°, and 101°, find the measure of the fifth angle.
First we have to find the sum of measurement of all the angles of a convex pentagon, by using the formula

Where n is the number of sides. And for polygon, it is 5 .SO the sum of measurement of angles of a polygon is

Let the measurement of missing angle be x .
So we have
