Question

find the magnitude and direction of the resultant vector for the diagram? HELP!

Answer 1

resultant vector is result of adding "x" components and "y" components
\[R_x = 14 \cos(104) + 21 \cos(20)\]
\[R_y = 14 \sin(104) + 21 \sin(20)\]
magnitude:
\[F = \sqrt{R_x^{2} + R_y^{2}}\]
direction:
\[\theta = \tan^{-1}( \frac{R_y}{R_x})\]
