ABC ~ XYZ. The ratio of their areas is 25/16. If XY has a length of 40, what is the length of AB? answer ASAP please

62.5

Step-by-step explanation:

From the question, we ware told that triangle ABC is similar to XYZ

Hence Aabc/Axyz = AB/XY

Substitute the given values

25/16 = AB/40

Cross multiply

16AB = 40 * 25

16AB = 1000

AB = 62.5

Hence the length of AB is 62.5

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
