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!
