true value of dip at a place is 45 degree.the plane of the dip circle is turned through 60 degree from the magnetic meridian.find apparent value of dip?please explain me the question with the help of figure a and give its solution.

If the plane of the scale of the dip circle is not in the magnetic meridian, then the needle will not indicate the correct direction of earth's magnetic field. The angle made by the needle with the horizontal is known as the magnetic dip.
