## highschoolmom2010 2 years ago An escalator lifts people to the second floor of a building, 25 ft above the first floor. The escalator rises at a 30 degree angle. To the nearest foot, how far does a person travel from the bottom to the top of the escalator?

3. hobbs978

this is another 30 60 90 triangle |dw:1375835469636:dw|

4. highschoolmom2010

yes

5. hobbs978

|dw:1375835598315:dw| this is what we are looking for :)

6. highschoolmom2010

12. hobbs978

no problem :)

I think the question how far does a person travel from the bottom to the top of the escalator? is the distance along the hypotenuse |dw:1375835842037:dw|

14. hobbs978

oh i was think how far he traveled in the building |dw:1375835934725:dw|
