Answer:
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
