* farthest right position on the wheel is given by h(t) = 45 sin(30t) + 60.

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52

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.
