__units

Answer 1

x = 28 units

Explanation:

We need to find the value of x.

The given triangles are similar triangles.

So, the ratio of corresponding sides are same.

`(x)/(10)=(42)/(15)`

Solving this equation we can find value of x.

`(x)/(10)=(42)/(15)\\Cross\:Multiply\\15x=42*10\\15x=420\\x=(420)/(15)\\x=28`

So, we get x = 28

So, we get the value of x: x = 28 units
