I need to find the resultant force on a bolt.?

F1 is 600N, 70degrees..F2 is 400 N, 20 degrees...and F3 is 500N, 60 degrees.
The answer is 69.6N, 154.1degrees but i dont now how to do it. Please help!

Answer:
please check your question again.

with the info provided, all the forces are in the first quadrant if the angles are measured from the horizontal

the x component of these forces = (600*cos70)+(400*cos20)+(500*c... = 831.09N to the right

the y component of these forces = (600sin70)+(400sin20)+(500sin6... = 113.36N upward

the resultant is the sq root of the sums of the squares
sq root(831.09^2+113.36^2) = 838.78

the angles from the horizontal is the arctan of 113.36/838.78 = 7.7 degrees above the x axis.

I think if your answer is correct, one of the forces or angles may be incorrect.
