Answer 2

as last:

x² + 5² = 9²

x² = 56

x = √56

x = 7.48

Answer 3

same thing i showed you

Answer 4

use the pythag theorem a^2+b^2=c^2

Answer 5

x^2 + 5^2 = 9 ^2

x^2 =56 ==> x=7.48

Answer 6

5^2+x^2=9^2

Answer 7

@felavin

Answer 8

yea what he said and just simplify

Answer 9

but it says to not solve the equation so just use, \[\sqrt{81-25}\]

Answer 10

4^2 + 8^2 = b^2 ==> b^2=80 ==> b=8.94

Answer 11

it gives no 8 as an option

Answer 12

you're not really going to learn how to do it by just getting the answer ._. also if you're gonna do it that way
