Put the percent in decimal form, than mutiply it by 360 degrees.
the measure of the inscribed angle is______ its corresponding central angle

You find central angle by using proportions. Part/Whole = x/360 Then, cross multiply and divide.
The central angle of the circle is the angle around a point and so, be definition, it must be 360 degrees.

The entire circumference has a central angle of 360 degrees. The arc is a fraction of the circumference. The fraction is (central angle) divided by (360). So the arc length is: (circumference) x (central angle) / (360) .
