Find the direction angle of vector v to the nearest tenth of a degree. show work #19

The vector v is given by:
 v = (7, 2) - (-5, 0)
 v = ((7 - (- 5)), (2-0))
 v = ((7 + 5), 2)
 v = (12, 2)
 Then, the direction angle of the vector is:
 tan (theta) = 2/12
 theta = atan (2/12)
 theta = 9.5 degrees
 
 The direction angle of vector v is:
 theta = 9.5 degrees
