Two straight lines cross at a point. One of the four angles formed there measures 118 degrees. How large is each angle that sits beside it along one of the lines?

Explanation

An angle beside the 118 degree angle completes a straight line with it, so it measures 180 minus 118, giving 62 degrees. Repeating 118 degrees describes the angle facing across the crossing instead of the neighbour that shares a line with it.
