Respuesta :

12.444 and b is 57.888

Answer:

Step-by-step explanation:

a) PQ' / PQ = 12/8 = 3/2

  Q'R' / QR = 15/10 = 3/2

  PR' / PR = 9/6 = 3/2

b) this means that triangle PQR is congruent to triangle PQ'R'. Because if we divide each side we get 3/2 (SSS)

c) because QR and Q'R' are parallel and they have same angles.
