2x + 7y =3 what is x and what is y

Consider the diagram. which line segment has the same measure as st? rx tx sr xs

Δabc is dilated by a scale factor of 3 with the origin as the center of dilation to form δa′b′c′. the slope of is -1.2. the length of is p units, the length of is q units, and the length of is r units. the slope of is . the length of is units.

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