The measure of angle ADE is 62°

In the diagram , since there are two pair of parallel lines , the quadrilateral is a parallelogram.

One of the properties of a quadrilateral is that the opposite angles are equal.

Another is that the adjascent sides of a parallelogram are supplementary.

Therefore angle A = 72

angle DEA = 46 ( alternate angles)

angle ADE will be

= 180 - ( 72+46)

= 180 - 118

= 62°

Therefore for angle ADE is 62°
