Find the measure of RST.

Answer: okay me learning this right now so okay

Step-by-step explanation: I worked on the same problem and got it right last time!

Given the major arc and the minor arc share the same chord, the angle RST will be:

∠RST=1/2∠RHT

∠RHT=1/3π=1/3*180=60

hence

∠RST=1/2*60=30°

Answer: 30°
