Question

The legs of a right triangle are 3 and 4 how do you find the length of the hypotenuse?

Answer 1

So, the hypotenuse is `color(red)(5`.

Explanation:

The Pythagoras theorem goes as follows:

`color(blue)(a^2+b^2 = c^2`

Here :`color(blue)(a=3, b=4`

`color(blue)(3^2+ 4^2 )= c^2`
`9+16 = c^2`
`25 = c^2`
`c = sqrt25 = 5`
So, the hypotenuse is `color(red)(5`.
