[SOLVED] Geometric Vectors 1. The problem statement, all variables and given/known data Find the magnitude and the direction (to the nearest degree) of the resultant of each of the following systems of forces. a. forces of 3 N and 8 N acting at an angle of 60º to each other - use geometric vectors to solve this problem Answer: 9.8 N, 15º to 8N 2. Relevant equations The cosine and sine laws. r = a^2 + b^2 - 2(a)(b)cosr sinθ/a = sinθ/b = sinθ/r 3. The attempt at a solution I tried using the sine law first, but I can't retrieve the angle to find the right resultant using the cosine law.
