ANSWER:
B. 23.96°
C. 236.31°
STEP-BY-STEP EXPLANATION:
To calculate the angle using the following formula:
[tex]\theta=\tan ^{-1}\mleft(\frac{A_y}{A_x}\mright)[/tex]We calculate in each case:
B.
[tex]\begin{gathered} \theta=\tan ^{-1}\mleft(\frac{1.60}{3.60}\mright) \\ \theta=\tan ^{-1}(0.444) \\ \theta=23.96\text{\degree} \end{gathered}[/tex]C.
[tex]\begin{gathered} \theta=\tan ^{-1}\mleft(\frac{2.00}{-3.00}\mright) \\ \theta=\tan ^{-1}(-0.66) \\ \theta=-33.69 \\ \theta=270-33.69 \\ \theta=236.31\text{\degree} \end{gathered}[/tex]
