When triangle abc is similar to triangle pqr, with a, b, and c corresponding to p, q, and r, respectively, it is customary to write abc ∼ pqr. suppose that ab = 4, bc = 5, ca = 6, and rp = 9. find pq and qr.

PQ = 6 and QR = 7.5

Step-by-step explanation:

The lengths of the sides of two similar triangles are proportional. That is, if Δ ABC is similar to Δ PQR, then the following equation is established.

PQ = 6

QR = 7.5

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
