SAT Practice Test 9 Math Section 2 Question 9. A circle has center O. Points R and S lie on circle

A circle has center O, and points R and S lie on the circle. In triangle ORS, the measure of angle ROS is 88 degrees. What is the measure of angle RSO, in degrees. (Disregard the degree symbol when entering your answer.) When Evil Testing Service describes a figure but doesn’t have the common decency to show you the figure, you have to draw the figure yourself. Then, write on the figures you have drawn. In triangles, equal sides are across from equal angles. (And equal angles are across from equal sides.) Big angles are across from big sides. What do you think small sides are across from? Small angles.
