an escalator lifts people to the secomd floor, 25ft above the first floor. the escalator rises at a 30 degree angle. how far does a person travel from the bottom to the top of the escalator?

• perpendicular=25ft
  angle=30degree
  so hypo=distance traveld from bottom to top(imagining the side of escalator as a right angled triangle)
  so sin 30=1/2=perpndicular/hypo
  hypo=perpendicular*2=25*2=50ft has to be travelld
