Question

Clarify please
A dog walk is used in dog agility competitions. In this dog walk, each ramp makes an angle of 30° with the ground. Find the length of one ramp and the length of the entire dog walk, including both ramps.
is it asking for the hypotenuse of the triangles or the longer leg... thanks.

Answer 1

the answer is here
let be L the length of each ramp
so the the length of the entire dog walk, including both ramps is D, such that
D=L + L + d, where d=12ft
L=hypotenus, and sin30° = 4.5ft x L so L= sin30° / 4.5= 1/2x 4.5=2.25ft

D=2.25ft+2.25ft +12ft=16.5ft
