Accepted Solution
A:
ANSWERB. 310°EXPLANATIONThe sum of angles in a circle is 360°From the diagram, the measure of arc SY is 50°The measure of arc STY plus the measure of arc SY is 360°To find the measure of arc STY, we subtract 50° from 360° to get:Measure of arc STY [tex] = 360 \degree - 50 \degree[/tex]This simplifies to[tex]310 \degree[/tex]The correct answer is B 310°
