, find the measure of minor arc arc, R, T, .
RT
The measure of the minor arc RT can be calculated by subtracting the measure of angle RST from 360 degrees.
Measure of minor arc RT = 360 degrees - Measure of angle RST
Measure of minor arc RT = 360 degrees - 122 degrees
Measure of minor arc RT = 238 degrees
