Answer 1

18

_____________________________________________________

Detailed explanation

`82^(2) = 6724`

`80^(2) = 6400`

We would simply need to subtract the numbers above.

6724-6400= 324

Now, we would need to square root 324.

`√(324)=18`

Hence, that is how 18 would be the answer.

Answer 2

82^2= 80^2+ x^2

x^2= 6724-6400
x^2=324
x=18

so option 1 is correct
