Answer 1

x = `40/3` , or `13` `1/3`

Explanation:

This is a similar triangle problem. You can assume that the triangle with sides 6cm, 8cm and y, is proportionally similar to the triangle with sides (6cm + 4 cm), x & z.

One setup is as follows:

`6/8 = 10/x`

then

`6x = 80`

then

`x = 80/6 = 40/3 = 13` `1/3`
