Plsss help meeeeeeee

Answer 1

Answer:

x = $\sqrt{99}$

Step-by-step explanation:

Based on the Pythagoras theorem, where a and b are the legs of the triangle and c is the hypotenuse.

$c^{2}= a^{2} + b^{2} \\c = \sqrt{a^{2} + b^{2} } \\x = \sqrt{7^{2} + (5\sqrt{2})^{2}} \\x = \sqrt{99}$

Therefor x = $\sqrt{99}$
