In the figure, point is the center of the circle, the measure of angle $RTB$ is 29 degrees, and the measure of angle $ROB$ is three times the measure of angle $SOT$. What is the measure of minor arc $RS$, in degrees?
Let angle SOT intercept an arc of x and let ROB interscept an ard of 3x
So
29 = (1/2) ( 3x - x)
58 = 2x
x = 29
3x = 87
And minor arc RS = 180 - 29 - 87 = 64°
