Explanation:

Answer 2

The answer is

`x = 12 \\ y = 20 \\ z = 15`

Explanation:

By using Pythagoras low

Then we can find that

`{y}^(2) = {x}^(2) + {16}^(2) \\ {z}^(2) = {x}^(2) + {9}^(2) \\ {y}^(2) + {z}^(2) = {25}^(2) \\ then \\ {x}^(2) + {9}^(2) + {x}^(2) + {16}^(2) = {25}^(2) \\ 2 {x}^(2) = 288 \\ x = 12 \\ By \: substituting \: x \: into \: the \: previous \: equations \\ then \: \\ y = 20 \\ z = 15`
