Δabc is similar to δaxy by a ratio of 5: 3. if bc = 25, what is the length of xy?

I think its XY=15.

Step-by-step explanation:

B; XY = 15

Step-by-step explanation:

if BC:XY and the ratio is 5:3, it would equate to 25:XY.

considering that the ratio of 5:3 and 25:XY are equal, whatever is done to one side must be done to another.

5 times 5 will make 25, so we must multiply the 3 by 5 to find XY

3 times 5 = 15, therefore XY = 15

you will see that the ratio 5:3 is equal to 25:15

therefore the answer is B

sorry, i can't understand your question. will later if you describe more clearly!
