1. Find the magnitude of the resultant (A + B) and its direction due East (counterclockwise from the +x-axis) of the following forces: A = 10N , 60 North of East and B = 7 N, 370 , East of South. Use cos law and sine law. 2. Find the magnitude of the resultant (A - B) and its direction due East (counterclockwise from the +x-axis) of the following forces: A = 12N , 60 North of West and B = 5 N. 479. South of West. Use cos law and sine law. 3. Find R and O by component method: A = 10ON, N B- 20ON, 36' W of N C = 90 N. 70' E of S D - 150 N. 53' W of S
