Question

The two

triangles are similar.

What is the value of x?

Enter your answer in the box:

Answer 1

x = 5

Explanation:

Sides of large triangle: 4x and 15

Corresponding sides of small triangle: 3x + 1 and 12

`(4x)/(15) = (3x + 1)/(12)`

`60 * (4x)/(15) = 60 * (3x + 1)/(12)`

`16x = 15x + 5`

`x = 5`
