F6 is a factor of a number what other numbers must be factors of the other number

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.

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.

The legs of a right triangle measure 6 meters and 8 meters. what is the length of the hypotonuse.
