How to find the angle of the resultant when 3 vectors are given? Do we do it like first we find angle of resultant of any of the two vectors and then treat that resultant as vector and find its angle with the remaining 3rd vector?

Solution

$Angle of the resultant : θ = \tan^{- 1} \frac{\sum F_{y}}{\sum F_{x}} where \sum F_{y} = Sum of y - components of all vectors \sum F_{x} = Sum of x - components of all vectors$
