Question

How do I find the length of the missing side for this right triangle?

Answer 1

`c = 5`

Explanation:

You use the Pythagorean theorem:
`a^2 + b^2 = c^2`.

Since we have the value of
`a = 3` and
`b = 4`..

Then we know that:

`a^2 + b^2 = 3^2 + 4^2 = 9 + 16 = 25 = c^2`

Since we know that
`c^2` is now, we take square root of that to get value of
`c`.

`√(c^2)=√(25)\\\\c = 5`
