$x = 502.4$ m
Since we have the measure of one angle and the measure of the side opposite to that angle, we can use the tangent ratio to find $x$, which is the side adjacent to the given angle. The tangent ratio is given as follows: tan $A = \frac{opposite}{adjacent}$ Let's plug in what we know: tan $22^{\circ} = \frac{203}{x}$ Multiply each side by $x$: tan $22^{\circ}(x) = 203$ Divide both sides by tan $22^{\circ}$: $x$ = 203/tan $22^{\circ}$ Divide to solve: $x = 502.4$ m
