here's the problem:
The magnitude and direction of two forces acting on an oject are
-70 lbs, S56[degree]E and
-50 lbs, N72[degree]E.
find the magnitude, to the nearest hundredth of a pound, and the direction angle, to the nearest tenth of a degree, of the resultant force.
i did this problem like 5 times! i keep getting different answers.
the answer in the back of the book is 108.21 lbs, S77.4[degree]E.
could someone explain it to me?
