If the wwight of a package is multiplied by 7/10 the result is 65.8 find the weight of the package

Given sin28.4=.4756, cos28.4=.8796, and tan28.4=.5407 find the cos of 61.6

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.
