87 degrees
It is: 15 degrees
The interior angle and central angle are supplementary, that is they always add up to 180 degrees, while the exterior angle and the central angle will always be the same.
An angle that measures 180 degrees is called a straight angle.
Each exterior angle measures 15 degrees Each interior angle measures 165 degrees
Each interior angle measures 150 degrees Each exterior angle measures 30 degrees
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.
The central angle of a circle is formed by two radii that extend from the center of the circle to its circumference. The intercepted arc is the part of the circle's circumference that lies between the two points where the radii intersect the circle. The measure of the central angle is equal to the measure of the intercepted arc in degrees. Thus, if the central angle measures θ degrees, the intercepted arc also measures θ degrees.
