Answer:
C. 5
Explanation:
We have been given an image of two triangles. We are asked to find the scale factor of ABC to UVW.
To find the scale factor of our given triangles, we will divide one side of triangle UVW by its corresponding side of triangle ABC.


Upon dividing both sides of equation by 5, we will get:


Therefore, the scale factor of triangle ABC to triangle UVW is 5 and option C is the correct choice.
