How do you get an 80ft mast under a 65ft bridge??

Here are some hints:

PI = 3.141592... (approximately 22/7 = 3.1428)
radians = degress x PI / 180 (deg to rad conversion)
degress = radians x 180 / PI (rad to deg conversion)

Extra points for the 1st to name the musical score..
Ummm.....

Why not just tie the weight/float to a rope which is slightly less than 65 ft combined length?
(Adjust rope length to allow for whatever margin of error is desired.)
Just keep tipping until the water is reached.

Don't even need to know the exact height of the mast.
The vector of gravity will address the rope alignment.
(Any drag on the float will just result in extra clearance.)

Going under a 62 ft bridge?
Use 3 ft less rope.

Good mathematicians are exeedingly lazy.
