Answer:

  • a) because all the angles of both of the triangle of equal and help by angle angle similarity criteria we can say that ∆ABCis similar to ∆PQR
  • b) since ∆ABC~ ∆PQR
  • [tex] \frac{ab}{ac} = \frac{pq}{pr} [/tex]

[tex] \frac{6}{ac } = \frac{18}{27} \\ ac = \frac{6 \times 27}{18 } \\ ac = 9cm[/tex]

Hope it helps you<3
