Answer 1

`5√(5)`
ROUNDED: 11.18

Explanation:

Use the Pythagorean Theorem to solve for a right triangle:
`a^(2) +b^(2) =c^(2)`

The legs are "a" and "b".

The hypotenuse (diagonal across from the right angle) is "c".

To start, fill in the values for the formula, then simplify.

`a^(2) + 10^(2) = 15^(2)`

`a^(2) + (100) = (225)`
Subtract 100 from both sides to leave
`a^(2)` by itself:

`a^(2) = 125`

Next, take the square root of each side.

`\sqrt{a^(2) } = √(125)`
The ^2 and square root cancel out for "a", giving you:

`a=√(125)`

Now, depending on if you need your answer in radical form or not, we simplify
`√(125)` to get your answer.

In radical form, simplify it to get:
`5√(5)`

In decimal form, take the square root of 125 and round to the needed value (likely tenths or hundredths). You should also round your answer, giving you: 11.18

Answer 2

a would be the square root of 325 or as a decimal it would be 18.0277563773

I used the a squared plus b squared equals c squared method so since 15 would be c and 10 would be a then 15 squared minus 10 squared equals 325 squared so the answer would be the square root if that
