7-115.

For the figure at right, determine if the two triangles are congruent. If so, create a proof (flowchart or two‑column) to explain why. Then, solve for . If the triangles are not congruent, explain why not. 

Two right triangles, A,B,C, & C,D,e. The short side, C E, of the second triangle, is part of the first triangle's hypotenuse, A C. Labels as follows: Long leg, B C, 40, short leg, A B, 9, Section, A E, labeled, x, hypotenuse, D E, 41, long leg, C D, 40.

Draw the triangles separately. What is ? What is ?
