Put the 7 on the x axis
then the 6 is at 135 which is 45 degrees above the -x axis
The x component of the resultant is 7 - 6 cos 45 = 2.757
The y component is 6 sin 45 = 4.243
the tan of the angle above the x axis = 4.243/2.757
so the angle is 57 degrees above x axis (above 7 vector)
and the magnitude is sqrt (2.757^2+4.243^2)
