For three vectors, find the magnitude and direction of the vector vector D $=$ vector A $-$ vector B $+3$vector C $.$ vector A of length $6\mathrm{.}7$ and pointing $54\backslash$deg up from the negative$-$x axis, vector B of length $7\mathrm{.}4$ and pointing $32\backslash$deg up from the positive$-$x axis, and vector C of length $2\mathrm{.}7$ and pointing $59\backslash$deg down from the positive$-$x axis.

Please find magnitude and direction.
