Three Vectors $\overrightarrow { \mathrm { S } }$ $\overrightarrow { \mathrm { T } }$

Three vectors, $\overrightarrow { \mathrm { S } }$ , $\overrightarrow { \mathrm { T } }$ , 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? $\begin{array} { | c | c | c | } \hline & x \text { component } & y \text { component } \\\hline & & \\\overrightarrow { \mathrm { S } } & & \\& - 3.5 \mathrm {~m} & 4.5 \mathrm {~m} \\\hline \overrightarrow { \mathrm { T } } & 0.00 m&-6.5 m \\\hline \overrightarrow { \mathrm { U } } & 5.5 m& -2.5 m \\\hline\end{array}$

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