How can you change a central angle into a percentage?

360 degrees = 100% so divide the angle's measure, in degrees, by 3.6.360 degrees = 100% so divide the angle's measure, in degrees, by 3.6.360 degrees = 100% so divide the angle's measure, in degrees, by 3.6.360 degrees = 100% so divide the angle's measure, in degrees, by 3.6.


What is the name of a central angle?

A central angle is an angle whose vertex is at the center of a circle and whose sides (or rays) extend to the circumference, effectively subtending an arc on the circle. The measure of a central angle is equal to the measure of the arc it subtends. For example, if the central angle measures 60 degrees, the arc it subtends will also measure 60 degrees.

If an angle that has a measure of 51.4 degrees is inscribed in a circle what is the measure of its intercepted?

102.8 degrees I think but it depends. If the angle is a central angle it is 51.4 degrees but other than that I think it would be 102.8 degrees.
