The answer is 54.

Step-by-step explanation:

Ok buddy

‣Remember that a right angle equals 90 degrees.

‣The numbers lie on a right angle.

‣So watchya gonna do is combine the like terms.

$x + 2x + 2x = 5x$

‣In an equation, that finna look like:

$5x = 90$

‣Solve that equation

$\frac{5x}{5} = \frac{90}{5} \\ \\ x = 18$

$3x \\ 3(18) \\ 54$

‣That fr is the answer, 54.
