(25 POINTS) PLEASE HELP WILL GIVE BRAINLIEST, THANKS AND 5 STAR RATING!!!

Answer 1

$PYTHAGOREAN THEOREM\\c^{2} = a^{2} + b^{2}\\ b^{2}=c^{2} -a^{2}\\ a^{2} =b^{2}-c^{2}$

1) x=9, because we can use the Pythagorean theorem, x^2 + 144 = 225, x^2 = 81

2) $x=3\sqrt{8}$, because 6^2 +6^2 = 72, $\sqrt{72} = 3\sqrt{8}$

3) $x=2\sqrt{3}$, because $x^{2} +7=19\\x^{2} =12\\x= 2\sqrt{3}$

hope this helps... load for images!
