Answer 2

AC = 3
`√(5)` ≈ 6.71

Explanation:

using Pythagoras' identity in the right triangle.

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

AC² = AB² + BC² = 6² + 3² = 36 + 9 = 45 ( take square root of both sides )

AC =
`√(45)` =
`√(9(5))` =
`√(9)` ×
`√(5)` = 3
`√(5)` ← exact value

AC ≈ 6.71 ( to the nearest hundredth )
