Part D

Another friend claims that you can use the cosine ratio to find the height of the platform. Explain why his approach is or isn’t a reasonable approach to finding the height of the platform.

Part E

After testing out your skateboard ramp, you and your friends decide that it’s too steep. You decide redesign the ramp so that the angle of elevation is only 20 degrees. However, you want the length of the ramp to stay the same. In the new design, about how much farther will the ramp extend horizontally from the platform than in the original design? Show the steps that justify how you arrived at your answer.
