Question

What is m?

please help

Answer 1

Given:

`\Delta ABC\sim \Delta QRS`

To find:

The missing value of m.

Solution:

We have,

`\Delta ABC\sim \Delta QRS`

Corresponding parts of similar triangles are proportional.

`(AB)/(QR)=(AC)/(QS)`

Putting the given values, we get

`(m)/(10)=(2)/(4)`

`(m)/(10)=(1)/(2)`

Multiply both sides by 10.

`(m)/(10)* 10=(1)/(2)* 10`

`m=5`

Therefore, the value of m is 5.
