Two roads cross at a chowk in Lucknow. The angle on the east is twice the angle on the north, and these two angles are adjacent (linear pair) along one straight road. A traffic engineer needs the angle vertically opposite to the east angle. Find it.

Question

Accepted Answer

120. Let north = x, east = 2x. Linear pair: x + 2x = 180, 3x = 180, x = 60. East angle = 120°; its vertically opposite angle = 120°.
