[[Word List: Adjacent, Cosine, Hypotenuse, Opposite, Sine, Tangent]]

(a) In this scenario, the 1-foot height represents the ______________ side of the triangle.
(b) The ramp is the _________________ of the triangle.
(c) The correct trigonometry ratio to use for this scenario is ____________.

(d) What is the proper length of the ramp if the angle is 5 degrees? Show work and round to the nearest tenth of a foot:

(e) The builder has wood that is 12 feet long but he doesn't want to cut all the wood. The ramp angle must not exceed 5 degrees. If the builder uses the 12 ft long wood to build the ramp (without cutting it) what will the angle be at the ground? Show work and round to the nearest tenth of a degree.

Bonus Question: Convert your answer from part (d) above to feet and inches. show work/explanation.
