1. In the diagram below, line AB is parallel to line CD, that is, LAB II LCD- The measure of LABC is 28, and the measure of LEDC is 42. Find the measure of CED. Explain why you are correct by presenting an informal argument that uses the angle sum of a triangle. 28 42" 2. In the diagram below, line AB is parallel to line CD, that is, LAB Lco- The measure of LABE is 38, and the measure of LEDC is 16". Find the measure of BED. Explain why you are correct by presenting an informal argument that uses the angle sum of a triangle. (Hint: Find the measure of 2CED first, and then use that measure to find the measure of BED.) 38 1.
