Question
Which equation can be used to find the measure of an angle that is supplementary to ∠POS?
A diagram is shown with line P T running horizontally and ray O Q extending upward at the center. A small blue square marks angle P O Q. Line S O R extends from the lower left to the upper right.
A. m∠POS + m∠POQ = 180º
B. m∠POS + m∠POR = 180º
C. m∠POS + m∠ROT = 180º
D. m∠POS + m∠QOT = 180º
