Multiple Choice

Three vectors, $\overrightarrow { \mathrm { S } }$ , $\overrightarrow { \mathbf { T } }$ , and $\overrightarrow { \mathrm { U } }$ , have the components shown in the table. What angle does the resultant of these three vectors make with the +x-axis? $\begin{array}{|c|c|c|}\hline & x \text { component } & y \text { component } \\\hline \begin{array}{c}\overrightarrow{\mathrm{s}} \\\end{array} & -3.5 \mathrm{~m} & 4.5 \mathrm{~m} \\\hline \begin{array}{c}\overrightarrow{\mathrm{T}} \\\end{array} & 0.00 \mathrm{~m} & -6.5 \mathrm{~m} \\\hline \begin{array}{c}\overrightarrow{\mathrm{U}} \\\end{array} & 5.5 \mathrm{~m} & -2.5 \mathrm{~m} \\\hline\end{array}$

A) 24° above the +x-axis
B) 24° below the +x-axis
C) 66° above the +x-axis
D) 66° below the +x-axis
