This figure shows circle O with diameter QS . mRSQ=310°What is the measure of ∠ROQ ?Enter your answer in the box._______

To solve this problem you must apply the proccedure shown below:

 1. The problem gives you the following information:

 - The circle O has a diameter QS.
 - The measure of RSQ is 310 degrees (m∠RSQ=310°).

 2. Then, you have that the measure of ∠ROQ is:

 ∠ROQ=360°-m∠RSQ
 ∠ROQ=360°-310°
 ∠ROQ=50°

 3. Therefore, as you can see, the answer is: ∠ROQ=50°
