Answer:

The hypotenuse is measured at 120 meters of string, and you need to solve for the leg of the triangle that is horizontal. The degree is 40, so use trigonometry to figure it out.

Cosin (40) is equal to around .766

Adjacent/Hypotenuse

x/120 = cos40

Answer: 91.92533.

If you use 3 significant figures it should be 91.9 meters.
