The calculation shows that the measure of the angle represented by x is approximately
\(33.69^\circ\), which is closest to 34°.

Sure, to find the angle x, we use the tangent function based on the sides of the right-angled triangle formed by Sid's directions.

Given:

Opposite side (height) = 2 miles

Adjacent side (base) = 3 miles

The formula for the tangent of an angle in a right triangle is:


\[\tan(x) = \frac{\text{Opposite}}{\text{Adjacent}} = (2)/(3)\]

To find x, take the arctangent (inverse tangent) of both sides:


\[ x = \tan^(-1)\left((2)/(3)\right) \]

Using a calculator:


\[ x \approx \tan^(-1)\left((2)/(3)\right) \]


\[ x \approx 33.69^\circ \]


\[33.69^\circ \approx 34^\circ \]

As you can see from the given figure, it is a right-angled triangle.

We are asked to find the measure of angle x.

We know from the trigonometric ratios that


\tan (x)=(opposite)/(adjacent)

Let us find the angle x


\begin{gathered} \tan (x)=(opposite)/(adjacent) \\ \tan (x)=(2)/(3) \\ x=\tan ^(-1)((2)/(3)) \\ x=33.69\degree=34\degree \end{gathered}

Therefore, 34° is the closest to the measure of angle x.
