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 is the magnitude of the resultant of these three vectors? $\begin{array} { | c | c | c | } \hline & x \text { component } & y \text { component } \\\hline \overrightarrow { \mathrm { S } } & & \\& 3.50 \mathrm {~m} & - 4.50 \mathrm {~m} \\\hline \overrightarrow { \mathrm { T } } & & \\& 2.00 \mathrm {~m} & 0.00 \mathrm {~m} \\\hline \overrightarrow { \mathrm { U } } & & \\& - 5.50 \mathrm {~m} & 2.50 \mathrm {~m} \\\hline\end{array}$
