What is the measure of angle CED? There are two triangles labeled ABC and DCE with a common vertex C. In triangle ABC, angle BAC
is labeled as m, and angle ABC is labeled as 60 degrees. In triangle DCE, angle CDE is labeled as 60 degrees. m, because Triangle ABC is similar to triangle EDC m over 2, because Triangle ABC is congruent to triangle DCE m + 60 degrees, because Triangle ABC is similar to triangle DCE 120 degrees − m, because Triangle ABC is congruent to triangle DCE
Answer: A standard equation is set up like this: Ax + By = C (where A, B, and C represent numbers). To find the slope (or the rate at which something changes) you must divide the value of A by the value of B (A / B).
