Please help on this i’m so confused

Answer 1

To find the scale factor between triangle A and triangle B, you can compare their corresponding side lengths.

Let's compare the corresponding sides of triangle A and triangle B:

A:

Legs: 5 and 12

B:

Legs: 15 and 36

To go from triangle A to triangle B, you can see that the corresponding sides of triangle B are 3 times longer than the sides of triangle A.

So, the scale factor is 3.
