Three rays OA, OB and OC are drawn from point O on one side of a straight line such that the three adjacent angles are 50°, 70° and x deg and together they make a straight line. Find x.

Question

Accepted Answer

60. Angles on one side of a straight line at a point add to 180°: 50 + 70 + x = 180, so x = 60°.

Three rays OA, OB and OC are drawn from point O on one side of a straight line such that the three adjacent angles are 50°, 70° and $x$ deg and together they make a straight line.
