Answer:
Step-by-step explanation:
Please consider the attached graph of circle.
We have been given that circle H has a radius of 3 centimeters. The length of minor arc RT is . We are asked to find the measure of angle RST.
We will use arc length formula to find central angle.
, where theta is central angle in radians.
Upon substituting our given values in arc length formula, we will get:
We know that the measure of inscribed angle is half the measure of central angle.
The measure of angle RST is in radians, we will convert it in degrees as:
Therefore, measure of angle is in radians or 20 degrees.
