Explanation:</h2>
<em>The height of the rider from the ground after the Ferris wheel</em> equals <em>the starting point is 15 feet off the ground </em><em>plus </em><em>the radius of the Ferris wheel </em><em>plus </em><em>the opposite side of the triangle ΔABC </em>(See figure below).<em> </em>Hence our goal is to find this side. We have the angle
, therefore the angle ∠BAC = 165° - 90° = 75°. So this side can be found using trigonometry:

Finally, the height is:

1/2y=7/8+2/3
1/2y=7.3/8.3+2.8/3.8
1/2y =21/24+16/24
1/2y=37/24
y=37/12
