Answer: We can use the tangent function to determine the angle of elevation of the road:tan(theta) = opposite/adjacentIn this case, the opposite side is the vertical distance of 150 feet, and the adjacent side is the horizontal distance of 0.6 miles, which is equal to 0.6 x 5280 = 3168 feet.So, we have:tan(theta) = 150/3168Using a calculator, we can find:theta = tan^-1(150/3168)theta ≈ 2.71 degreesTherefore, the angle of elevation of the road is approximately 2.71 degrees.
