Question

Find the missing side length, m.

Answer 1

`m=6`

Explanation:

The Two triangles are Similar, so using the property of the similar triangles.

`(m)/(15) =(4)/(10)`

On cross multiplication of the fraction:

`10*m=4*15`

`10*m=60\\\\`

Dividing by '10' both the sides:

`(10m)/(10)=(60)/(10)`

`m=6`

So, the side(m) of the small triangle is '6'
