Answer:[tex]\theta =64.29^{\circ}[/tex]
Explanation:
Given
Vector Points -1.55 units along x-axis
i.e. 1.55 units along negative x-axis
and 3.22 units along Y-axis
Direction of vector
[tex]\tan \theta =\frac{3.22}{1.55}[/tex]
[tex]\theta =tan ^{-1}(2.077)[/tex]
[tex]\theta =64.29^{\circ}[/tex]
Where [tex]\theta [/tex] is the angle made by vector with x-axis as shown in the diagram
