Question

I need help. I will give 15 points for the answer.

Answer 1

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
• $\frac{ab}{ac} = \frac{pq}{pr}$

$\frac{6}{ac } = \frac{18}{27} \\ ac = \frac{6 \times 27}{18 } \\ ac = 9cm$

Hope it helps you<3
