angle of a wheelchair ramp may not exceed 4.764º. door is 5 feet above sidewalk level, how long must the ramp be in order to extend from sidewalk to door?

Question

Having trouble believing that the longest side of my triangle is 60 and the other two are 5 x 59.7, please help

Answer 1

sin(4.764º)=5/x where x is the length of the ramp or the hypotenuse of the right triangle

0.0830517=5/x

x=5/0.0830517

x=60.20346 feet

wheelchair ramp is "1 inch rise for every 12 inch length"

you have a 5 foot rise which is 60 inches of rise

60*12=720 inches of length which is 60 feet
