9. The three displacement vectors in the drawing have magnitudes of \( A=5.00 \mathrm{~m}, B=6.00 \mathrm{~m} \), and \( C=4.00 \mathrm{~m} \). a. If \( \vec{R}=\vec{A}+\vec{B}-\vec{C} \), find the magnitude and directional angle of resultant vector \( \vec{R} \) by means of the component method. Express the directional angle as an angle above the positive or negative \( x \) axis (please specify). b. Write \( \vec{R} \) using unit-vector notation
