Answer 1

n = 24

Explanation:

These triangles are mathematically similar

`n = 12/5 * 10`

`n = 24`

Answer 2

`n=24`

Explanation:

The triangles are similar so their sides are in the same ratio.

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

`5/10 = 12/n`

By observation we can see that the denominators are double the numerators, giving `n = 24`

However if we solve for `n` by cross-multiplying we get:

`n = (10xx12)/5`

`n = 24`
