The vertices of a triangle are a(7,5), b(4,2), c(9,2). what is m

The figures below are made out of circles, semicircles, quarter circles, and a square. find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations).

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?
