Question

If (Triangle)ABC is similar to (Triangle)EDC, what is the value of x?

Answer 1

37.5 (G)

Explanation:

Set up a proportion:

`(40)/(100) = (15)/(x)`

Next cross multiply

`(15)(100) = (40)(x)`

`1500 = 40x`

Lastly solve for x by dividing both sides by 40

`(1500)/(40) = (40x)/(40)`

`x = 37.5`
