need help

if i have a right triangle and the opposite of x is 100 and the adjacent side to x is 150 what is the value of x?

$\begin{array}{rcll} \tan{(x)} &=& \frac{100}{150} \\ \tan{(x)} &=& \frac{10}{15} \\ \tan{(x)} &=& \frac{2}{3} \\ \tan{(x)} &=& 0.66666666667 \\ x &=& \tan^{-1}{(0.66666666667)} \\ x &=& 33.6900675260^{\circ} \end{array}$

Hint: What trig ratio is opposite over adjacent?
