Question

What is the value of x?

Answer 1

x = 4

Explanation:

Using similarity, we can set up a proportion and solve:

There are two triangles in this image, triangle ABC and triangle DEC.

`(x)/(10)=(6)/(15)`.

Cross multiply to get:

`15x=60`

Divide by 15 on both sides to get:

`x=4`

So, 'x' is 4.
