This document contains three math word problems involving parallel lines and angles. The first problem asks the reader to determine the size of an angle given that one line is parallel to another and one angle measures 36 degrees. The second problem involves finding the measures of two angles given information about parallel lines and additional angles. The third problem asks the reader to calculate the measure of an angle within a shape formed by parallel lines where some angle measures are given.
