Question

What is the measure of ∠CED?

There are two triangles labeled ABC and DCE with a common vertex C. In triangle ABC, angle BAC is labeled as b, angle ABC is labeled as 50 degrees. In triangle DCE, angle CDE is labeled as 50 degrees.
b over 2, because Triangle ABC is congruent to triangle EDC b, because Triangle ABC is similar to triangle EDC b + 50 degrees, because Triangle ABC is similar to triangle EDC 130 degrees − b, because Triangle ABC is congruent to triangle EDC
