Answer 1

`3√(5)`

Explanation:

Since the triangle has a right angle, we are going to use pythaogoran theoem, which is
`a^(2) +b^(2) =c^(2)`, where a and b are the legs and and c is the hypotunese/ slated side. Let set it up.

`3^(2) +6^(2) =c^(2)`

9+36=c^2

45=c^2

`√(45)`=

Then we are going to find a perfect squarre root(1,4,9,16,25....) to simplify the radical

The perfect square root is 9 because 9 goes into 45 5 times.

`√(9x5)`

Then take the sqr root of 9 and we have
`3√(5)`
