Question

If a= 2ft and c= 11ft. Find the missing side of the right triangle

Answer 1

`√(117)` or
`3√(13)`

Explanation:

The formula for finding the any side of the triangle is

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

We know that a=2 and c=11, so we can go ahead and plug those into the formula.

`2^(2)+b^(2) =11^(2)`

`4+b^(2) =121`

To find side b, we have to make it alone on one side. Subtract 4 on both side.

`b^(2) =117`

Now square root both sides, and that leaves us with:

`b=√(117)` or
`3√(13)`
