#380 from OG 10th
In the circle below, PQ
is parallel to diameter OR
, and OR
has length 18. What is the length of minor arc PQ
I need help with understanding one thing. In the answer explanation it says that "since the measure of inscribed angle PRO
is 35 degrees, the measure of minor arc OP
is 70 degrees." Can somebody explain to me how that is figured out? In other words, how do you figure out the 70 degrees by knowing that PRO
is 35 degrees??
P.S. Sorry about my drawing skills...
