A straight trail with a uniform inclination of 17deg leads from a lodge to an elevation of 900 feet to a mountain lake at a elevation of 5500 ft. what is the length of the trail?
(im soo stuck on this problem)
let the length of the trail be t ft.
then t is the hypotenuse of a right-angled triangle of height 4600 ft
so sin 17 = 4600/t
t = 4600/sin17
= ... (don't have a calculator handy)
