Question

A)
Juaquin is building a bike ramp with blocks and a piece of plywood. He stacks two blocks, eachmeasuring 1 foot in height, on top of one other. He then places the plywood, which is 4 feet long, on anangle from the top of the blocks to the ground. Using the inverse of sine function, what is the angle ofelevation formed where the plywood rests on the ground? Round your answer to the nearest wholedegree.

You’re hiking in Zion National Park when you stop to look at a specific rock feature. The rock featureis 300 feet above the base of the mountain, and the diagonal distance between you and the rock featureis 750 feet. Using the inverse of sine, what is the angle of elevation you are using to look up at thefeature? Round your answer to the nearest whole degree.

Answer 1

1) sin⁻¹(2/4) = sin⁻¹(0.5) = 30°

2) sin⁻¹(300/750) = sin⁻¹(0.4) ≈ 23.6° ≈ 24°
