Answer: 1.5
Step-by-step explanation:
To find the scale factor from figure A to figure B, we can find the ratio of a pair of their corresponding sides.
Let's use the left side of both triangles. The ratio would be:
Left side of A : Left side of B
= 12 : 18
Now, simplify the ratio by dividing both sides by 12. We want the left side of the ratio to be 1 (A's side) since we are finding the scale factor from A to B:
1 : 18/12
= 1 : 1.5
This ratio means that a side of figure B is 1.5x larger than the corresponding side for figure A.
Therefore, the scale factor from figure A to figure B is 1.5.
