Four displacement vectors, A, B, C, and D, are shown in the diagram below. Their magnitudes are: A = 13.8 m, B = 11.0 m, C = 12.0 m, and D = 21.5 m.

Four displacement vectors, $$\overrightarrow{\mathbf{A}},\overrightarrow{\mathbf{B}},\overrightarrow{\mathbf{C}}$$, and $$\overrightarrow{\mathbf{D}}$$, are shown in the diagram below. Their magnitudes are: $$A=13.8\mathrm{m},B=11.0\mathrm{m},C=12.0\mathrm{m}$$, and $$D=21.5\mathrm{m}$$. What is the magnitude, in meters, and direction, in degrees, of the resultant vector sum of $$\overrightarrow{\mathbf{A}},\overrightarrow{\mathbf{B}},\overrightarrow{\mathbf{C}}$$, and $$\overrightarrow{\mathbf{D}}$$ ? Give the direction as an angle measured counterclockwise from the $$+x$$ direction. $$\begin{array}{ll}\text{ magnitude }& m\\ \text{ direction }& ?\end{array}$$
