Question

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

Answer 1

• 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
• 
  `(ab)/(ac) = (pq)/(pr)`

`(6)/(ac ) = (18)/(27) \\ ac = (6 * 27)/(18 ) \\ ac = 9cm`

Hope it helps you<3
