Question

Look at the picture

Answer 1

`3cm,5cm,9cm`

Step-by-step explanation:

`{c}^(2) = {a}^(2) + {b}^(2)`

`c = \sqrt{ {a}^(2) + {b}^(2) }`

`9 { = }^(?) \sqrt{ {3}^(2) + {5}^(2) }`

`9 { = }^(?) √(9 + 25)`

`9 { = }^(?) √(34)`

`9 \\eq 5.8309518948453`

`3cm,5cm,9cm`

Answer 2

C.

Explanation:

use the pythogorean theorem a^2 + b^2 = c^2
