Answer: the height of the ramp above the water at the highest point is 2.0832ft
Step-by-step explanation:
The ramp makes an angle of 10 degrees with water and forms a right angle triangle.
The height of the ramp above the water at the highest point represents the opposite side of the right angle triangle.
The length of the ramp represents the hypotenuse of the right angle triangle. Therefore, to determine the height of the ramp above the water at the highest point, h , we would apply the Sine trigonometric ratio.
Sin θ = opposite side/hypotenuse. Therefore,
Sin 10 = h/12
h = 12Sin10 = 12 × 0.1736
h = 2.0832
