As triangles are similar therefore the ratio of their corresponding sides are equal . In this case

9/c = 7.5/d

Cross multiply

9d =7.5 c

Now arrange

d/c = 7.5/9

d/c = 75/90

d/c = 5/6

MrGumby

The value of d/c is 5/6

In order to find this, we need to simply replace the values of the triangles that match up. The d portion would match up with 7.5 and the c portion would match up with the 9. So, we can put them into the equation and simplify.

d/c = 7.5/9

d/c = 5/6
