For the vector Squareroot 14 1 find the magnitude and direct

For the vector (Squareroot 14, -1), find the magnitude and direction angle (to the nearest tenth). Give the measure of the direction angle as an angle in (0, 360 degree).

Solution

given vector <14, -1>

magnitude =[(14)²+(-1)²]

magnitude =[14+1]

magnitude =15

direction =360^o-tan^-1(1_/14)

direction =345.0^o
