Answer 1

To find the scale factor, we can compare the corresponding side lengths of the two triangles.

The corresponding side lengths from the left triangle to the right one are:

10 in. to 20 in. (doubled)
15 in. to 30 in. (doubled)
36 in. to 18 in. (halved)

So, the scale factor is 2.

Hence, the correct answer is 2.
