Mr. Boline is building a ramp so that people in wheelchairs can access a building.
If the ramp must have a height of 8 feet, and the angle of elevation of the ramp must be 5°, how long must the ramp be?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

 = tan(5°)  --->  L = ,  if the length measures horizontally, as a leg of the right-angled triangle.


 = sin(5°)  --->  H = ,  if the length measures along the slope, as the hypotenuse of the right-angled triangle.


Unfortunately, the problem does not determine EXACTLY, which length is under the question.
