Just in advance ,not very good at it

The answer is legs
The side away from the right angle is the hypotenuse
If there is a specified angle you are looking at
The "hypotenuse" of that angle would be the opposite, and the one that is not the actual hypotenuse would be the adjacent
Fraction is 2.161616/1000000
mixed number is 2 161616/1000000
Work is force times distance. Note that the only work done here is in the direction opposed to gravity, or if you prefer the change in height times the weight...
W=3sin20(8*9.8)
W≈80.44 J
