Answer 1

Answer:
`a=√(60)`

Explanation:

To solve for a, we want to use Pythagorean Theorem as provided int eh problem. a and 2 are the legs while 8 is the hypotenuse.

`a^2+2^2=8^2` [exponent]

`a^2+4=64` [subtract both sides by 4]

`a^2=60` [square root both sides]

`a=√(60)`

Now we know that
`a=√(60)`.
