The Figure Shows Four Vectors $\vec { A }$ $\overrightarrow { \mathbf { B } }$

Short Answer

The figure shows four vectors, $\vec { A }$ , $\overrightarrow { \mathbf { B } }$ , $\overrightarrow { \mathrm { C } }$ , and $\vec { D }$ . Vectors $\vec { A }$ and $\overrightarrow { \mathbf { B } }$ both have a magnitude of 7.0 cm, and vectors $\overrightarrow { \mathrm { C } }$ and $\vec { D }$ both have a magnitude of 4.0 cm. Find the magnitude and direction of the sum of these four vectors.
