To estimate the number of people in springfield, population 10,000, who have a swimming pool in their backyard, 250 people were interviewed. of those polled, 119 had a swimming pool. how many people in the city might one expect to have a swimming pool? (round to the nearest whole number, if necessary.)

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.
