8.8 Trigonometry Word Problems

Here you’ll learn how to use the trigonometric ratios to solve word problems.

What if a restaurant needed to build a wheelchair ramp for its customers? The angle of elevation for a ramp is
recommended to be 5◦. If the vertical distance from the sidewalk to the front door is two feet, what is the horizontal
distance that the ramp will take up(x)? How long will the ramp be(y)? Round your answers to the nearest hundredth.
After completing this Concept, you’ll be able to use trigonometry to solve this problem.
