10-20.

For each of the geometric relationships represented below, write and solve an equation for the given variable. For parts (a) and (b), assume that $C$ is the center of the circle. Show all work. Homework Help ✎

Since both are radii, $5m + 1 = 3m + 9$.

$m = 4$

The measure of the central angle is twice the measure of the inscribed angle. So $2(x + 4) = 3x − 9$.

How are the sides of a right triangle related?

$p = 10$

What is the total sum of the angles of this polygon?
