Question 1 – Determine the resultant force and direction angles<\/h1>\n

If FB = 600 N and FC = 800 N determine the resultant force and the direction angles of the resultant force acting on the flag pole.\u00a0 \u00a0Hint – resolve the two vectors into Cartesian or i j k vectors first.\u00a0 You will need to find the unit vectors u AB and u AC.<\/p>\n
