Question 1075695: Need some help solving this word problem! --
Forces with magnitudes of 250 lbs and 130 lbs act as an object at angles of 45° and -60°, with the positive x-axis. What is the direction & magnitude of the resultant from these two forces? Thanks a lot.

You can put this solution on YOUR website!
F=(250cos%2845%29%2B130cos%28-60%29,250sin%2845%29%2B130sin%28-60%29)
F=(A,B)
A=250cos%2845%29%2B130cos%28-60%29
B=250sin%2845%29%2B130sin%28-60%29%29
Use a calculator to work out the values.
Then,
abs%28F%29=sqrt%28A%5E2%2BB%5E2%29
and
theta=tan%5E%28-1%29%28B%2FA%29
