If m<AOC=90 and m<AOB=20. Find m<BOC.
Answered by drwls
There must be a figure that goes with that question. It is not a triangle, since you have mentioned four points: A, B, C and O. Please describe the situation.

Does m< indicate the measure of an angle that follows, in degrees? I am not familiar with that notation.
