Answer:
142°
Step-by-step explanation:
Given is a circle with center O
A and R are points on the circumference
AOR is given as 142 degrees
AOR angle is nothing but the arc (minor) AR subtends at the center.
Hence the measure of AR = angle the minor arc AR subtends at the center
= 142 degrees
Central angles are subtended by an arc between those two points, and the arc length is the central angle of a circle of radius one (measured in radians). The central angle is also known as the arc's angular distance. The size of a central angle Θ is 0° < Θ < 360° or 0 < Θ < 2π (radians).
