4) Tiffany and Juan are given the task of designing a wheelchair ramp at the entrance of the County Courthouse. The rise has to be 5 feet and the angle of elevation of the ramp has to be 15 degrees. What will be the length of the ramp? 5) Mr. Smith noticed that he could spot his house from the top of Stone Mountain. If Mr. Smith noticed that he had to use a 20º angle of depression to spot his house and that Stone Mountain is 825 feet above its surroundings, then how far is the base of Stone Mountain from his house? 6) From a point 114 feet from the base of a redwood tree, the angle of elevation to the top of the tree is 64.3°. How tall is the tree? 7) The lighting technician needs to shine a spotlight onto the musician’s face during her solo. The light being directed is attached to a ceiling that is 10 feet above the musician’s face. What is the horizontal distance from the light to the musician’s face if the light is to shine down at an angle of 20o? What if the lighting technician wants to shine the light at an angle of 30°? 32°?
