Meteorology: The temperature is 8 degrees. It is expected to fall 5 degrees each hour for the next several
hours. In how many hours will the temperature be -7
degrees.
8-5= 3 + 7 = 10
I need step by step answers

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.
