ANSWER:
333.4°
STEP-BY-STEP EXPLANATION:
To find angle for a vector:
[tex]\theta=\tan ^{-1}\mleft(\frac{A_y}{A_x}\mright)[/tex]We substitute the values of this case and the angle would then be:
[tex]\begin{gathered} \theta=\tan ^{-1}\mleft(\frac{-2.10}{4.20}\mright) \\ \theta=\tan ^{-1}(-0.5) \\ \theta=-26.56\cong-26.6 \\ \theta=360-26.6 \\ \theta=333.4\text{\degree} \end{gathered}[/tex]The angle is 333.4°
