Two forces with magnitudes of 150 and 75 pounds act on an object at angles of 30° and 150° respectively. Find the direction and magnitude of the resultant force. Round to two decimal places in all intermediate steps and in your final answer.

Please explain how to get BOTH direction and magnitude. Thank you:)

any help would be fantastic:) im so confused with this problem

anonymous · Answer

Let x= magnitude
x= root(150^2+75^2-2(150)(75)cos(60))
x= 75(root3)

^this is what i have so far... i dont think its even remotely right

anonymous · Answer

just analyze them into x component and y component and add them with respecting to signs and the direction is simply the angle.

anonymous · Answer

can you explain how to do that? i have no clue what im doing :P
