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 n, angle ABC is labeled as 55 degrees. In triangle DCE, angle CDE is labeled as 55 degrees.

n, because Triangle ABC is similar to triangle EDC

n over 2, because Triangle ABC is congruent to triangle EDC

n + 55 degrees, because Triangle ABC is similar to triangle EDC

125 degrees − m, because Triangle ABC is congruent to triangle EDC
