Which is the following is a benefit of the water cycle to

correct it is c.) b b

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
