Sagot :

In order to find the values of x and y, consider that the triangles are similar. Then, the proportion between similar sides of the triangles are equal.

In triangles ABC and DEF you have:

EF/BC = ED/BA

by replacing the values of such sides you obtain:

x/28 = 7/14 multiply by 28 both sides

x = (7/14)(28)

x = 14

Hence, the value of x is x = 14

Next, for the same triangles use the following proportion:

AC/DF = BC/EF

by replacing the values of such sides you obtain:

y/10 = 28/14 multiply by 10 both sides

y = (28/14)(10)

y = 20

Hence, the value of y is y = 20
