Answer:
s = 10
______________
To get from 4 to 8, you multiply by two. Because the triangles are congruent, you would do the same thing with 5 to S. 5 * 2 = 10. So S = 10
*Hope this helped!! : ) have a great day or night wherever you are!*
Step-by-step explanation:
As the triangles are similar,
The sides are proportional too.
So, we can see that
Side AB is proportional to XY
So, XY side is half of AB.
So, BC will be 5×2 = 10
So, 10 is the correct answer.
