Determine the critical value(s) for a left-tailed test of a population mean at the α=0.01 level of significance based on a sample size of n=10.

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?

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.
