I need help please :(((( .

Answer 1

see explanation

Explanation:

If the ratios of the 3 pairs of corresponding sides of the 2 triangles are equal then the triangles are similar

`(15)/(5)` =
`(12)/(4)` =
`(9)/(3)` = 3

Then the triangles are similar by the SSS postulate

If 2 angles of 1 triangle are congruent to 2 angles of another triangle then the triangles are similar

∠ A = ∠ p = 27°

∠ B = ∠ Q = 45°

Then Δ ABC and Δ PQR are similar by the AA postulate
