Step-by-Step Solution
All angles on one side of line PQ at O sum to 180°. So angle COQ = 180 - (50 + 60 + 40) = 180 - 150 = 30°.
Answer: C) 30
Three rays OA, OB, OC are drawn on one side of line PQ from point O on it, with no overlaps. If angle POA = 50°, angle AOB = 60°, angle BOC = 40°, find angle COQ.
