8-8.

the geometric relationships in the diagram at right. Show all of the steps in your solutions for *x* and *y*. Homework Help ✎

*x* + *x* + *x* + *x* + *x* = 360° , because all of the central angles of the figure total 360°.

2*y* + *x* = 180°, because the Triangle Sum Theorem states the angles of a triangle total 180°.

*x* = 72°, *y* = 54°
