Using the formula: opposite side = hypotenuse * sin(theta), where theta is the angle between the hypotenuse and the opposite side, we can solve for the opposite side.
In this case, we know that the hypotenuse is 29 miles and the value of sin(theta) is given as 0.7536. Therefore, opposite side = 29 * 0.7536 = 21.8344 miles (rounded to four decimal places).
Therefore, the opposite side is approximately 21.8344 miles.
