HELP FOR 20 POINTSSS

x =3 ; y=8.4

x = 3 ; y = 15

x = 6 ; y =7.5

x = 6; y =18

Answer 1

The first one.

Explanation:

solving for x:

5/2 = 7.5/x

cross multiply

2 ×7.5 =5x

x= 2×7.5/5

x= 3

solving for y:

values of the small triangle over the bigger triangle-

5/6 =7/y

cross multiply and solve for y

y= 8.4

therefore (x= 3; y= 8.4)
