(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A vector has x component of (-25.0) units and y component of (40.0) units. Find the magnitude and direction of this vector.

2. Relevant equations

3. The attempt at a solution

Magnitude = [tex]\sqrt{}(-25.0)^2+(40.0)^2[/tex]

= 47.17 units.

Direction = tan x = | 40.0 | / |-25.0|

= 1.6

x = tan^-1 (1.6)

= 58

since the vector is located in the IInd Quadrant theta = 180 -58 = 122 degrees.

But text book answer is 58 degrees.I couldn't get it

Any suggestions ?? Thank you...
