The top of the cliff C is observed from A to have a vertical angle of 24 degrees. The observer then moves horizontally towards the cliff at point B, 1500m from point A and found out that the vertical angle of C is 45 degrees. A, B, and C lie on the same plane. Find the elevation of the cliff if the height of the instrument at A is 5.35m above the sea level.
