Answer 1

The missing length is:

`√(50)`

or

`5√(2)`

Explanation:

To solve for a length in a right triangle, we have to use the Pythagorean Theorem which states:

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

Where a and b are sides and c is the hypotenuse.

`7^(2) +1^(2) =c^(2)`

`49+1=c^(2)`

`c^(2) =50`

`c=√(50)`

`c=5√(2)`
