why did we use that root formula thing? shouldnt we just plus? is there an easie rway to solve

Top View The diagram shows the directions and magnitudes of the forees exerted on a puck on a horizontal surface. What is the magnitude of the vector sum of the forces exerted on the puck'? (A) 3N (B) 4N (Db) 7N Answer C Correct. The vector sum of the forces in the left-right direction has magnitude 4 N and the vector sum of the forces in the top-bottom-of-page direction has magnitude 3 N. The magnitude of the vector sum of the forces is then Fae = / (3N)? + (4N)? =5N
