Since the given triangle is a right triangle, we can solve the missing side using the trigonometric functions of the angle.

The trigonometric function that involves the two legs of the triangle and not the hypotenuse is the tangent.


\tan \theta=(op)/(ad)

then,


\tan 41=(20)/(x)

solve the equation for x


\begin{gathered} x=(20)/(\tan 41) \\ x=23.007\approx23.0 \end{gathered}
