Point A is correct, point B is incorrect. Point B is at a distance of 483 m from the point A in the azimuth of 118 degrees. We have to shift in rectangular ways according to longitude and latitude. Point A is therefore on the upper left, the point B on the lower right. Shift the Google map so that the the points overlay each other, i.e. northward and westward. When the azimuth is 118 degrees let's deduct the parallel (90 degrees) and we have 28 degrees at the point B. Total of angles in a triangle is 180°, we have a right angle 90° and calculated 28°. Remaining angle is 180 – 90 – 28 = 62°. For the shift to the North/South calculate the distance like this: distance = sinus of the B point angle x distance of the points, i.e. sin 28° x 483 = 226 m.
Put -226 into the North field (we are shifting the map southward) and 426 into the East field. Confirm and see that the points overlay each other.
