In the diagram below, tangentis perpendicular to diameter at . is the intersection of with the circle.
is a diameter with , , , and all collinear. If the measure of is more than the measure of , what is the measure of in degrees?
Lethave measure and measure . Thus .
is a diameter, so arcs and add up to . Therefore,
Combined with we can solve for and . Thus measures .
The correct answer is: 34
