Question

In the right triangle, AC = BC = 2. What is AB?

Answer 1

Formula for hypotenuse:

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

a would be AC
b would be CB
c is AB


`√(2^2+2^2)`

`√(4+4)`

`√(8)`

It is
`√(8)` or
`2 √(2)` or about 2.83

Answer 2

Use the Pyth. Thm.: x^2 = 2^2 + 2^2 = 8, so x = +sqrt(8) = +2sqrt(2) (ans.)
