Consider the three displacement vectors shown in the figure: Vector
has a magnitude of 8.30 km and a direction that makes an angle
= 24.0° to the left of the positive y-axis, vector
has a magnitude of 5.70 km and a direction that makes an angle of
=34.0° above the positive x-axis, and vector
has a magnitude of 3.50 km and a direction that makes an angle
= 60.0° below the negative x-axis. Determine the magnitude of the vector
