In the diagram below, line AB is parallel to line CD, that is, LABI LCD. The measure of LABE is 38°, and the
measure of LEDC is 16°. Find the measure of ZBED. Explain why you are correct by presenting an informal
argument that uses the angle sum of a triangle (Hint: Find the measure of ZCED first, and then use that measure
to find the measure of ZBED.)
