Find four consecutive odd integers if the sun of the first and fourth is 3 less than 3 times the second

What is the slope of the line shown below?

Given: circle o, cd is diameter, chord ab || cd. arc ab = 74°, find arc ca.

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.
