You have to put the two angles in the same units, because now the first one is in radians and the second one in degress.
To pass 1.38 radians to degrees you can use the ratio 180° / π radian = 1.
So 1.38 radian * 180° / 3,1416 = 79 °.
So the angle in the Column A is 2° wider than the angle in the Column B.
