Kayden had math and reading homework tonight. kayden can solve each math problem in 5 minutes and he can read each page in 1.5 minutes. write a system of equations that could be used to determine the number of math problems kayden solved and the number of pages he read. define the variables you use to write the system.

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
