Question 998493: Two forces have magnitudes of 21 N and 24 N and the angle between them is 65°. Find the magnitude of the resultant and the angle it makes with the larger of the two forces (1 dp)
resultant force (N) ≈
angle (°) ≈

.
resultant force = sqrt%2821%5E2+%2B+24%5E2+%2B+2%2Acos%2865%5Eo%29%2A21%2A24%29 = 37.523 N.

If you have a question why the sign is "plus" at cosines, make a sketch.
