Question 111782
The most efficient operating angle for a certain conveyor belt is 31 degree. If the parts must be moved a vertical distance of 16 ft, what length of conveyor is needed? Round to the nearest tenth.
Drawing given is a triangle: Right angle 16' opposite side 31 degree angle.
:
The length of the conveyor is the hypotenuse (h), 
therefore we can use the sine of 31 degrees (side opposite over hypotenuse):
:
sin(31) = {{{16/h}}}
.515 = {{{16/h}}}
.515h = 16
h = {{{16/.515}}}
h = 31.1 ft
