Question

H6) A straight trail with aNIEuniform inclination of 15°leads from a lodge at an elevation of1000 feet to a mountain lake at anelevation of 7800 feet. What is thelength of the trail (to the nearestfoot)?

Answer 1

see the image to better understand the problem

we have that

sin(15)=6800/L -------> by opposite side divided by the hypotenuse

solve for L

L=6800/sin(15)

L=26,273 ft
