What is the measure of angle tvu shown in the diagram below

The volume of gas a balloon can hold varies directly as the cube of its radius. imagine a balloon with a radius of 3 inches can hold 81 cubic inches of gas. how many cubic inches of gas must be released to reduce the radius down to 2 inches?

If angle ase measures 168 degrees, find the measure of angle dse. the figure mag not be drawn to scale
