What is length of rope on flagpole if adjacent side is 11.6 meters long and opposite angle is 36.8 degrees?

Answer 1

Let "x" be the length of the adjacent and "y" the length of the opposite. The flagpole height will be the opposite.

tan θ = y / x → y = xtan θ

11.6 tan 36.8° = 8.68 meters

The rope must be twice the length of the pole to raise and lower the flag.

2 x 8.68 = 17.36 meters
