Angela has 3 more dollars than half of sabrina's money. if angela has 206 dollars, how much does sabrina have? define your varieble and solve your your equation.

(plz solve this with explanations and how you can check your work)

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

Given: m∠ adb = m∠cdb ad ≅ dc prove: m∠ bac = m∠bca lol

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.
