A and B are summits of two mountains that rise from a horizontal plain. B being 2200 meters above the plain. Find the height of A, it being given that its angle of elevation as seen from a point C in the plain ( in the same vertical plane with A and B ) is 60 degrees, while the angle of depression of C viewed from B is 38 degrees 58 minutes and the angle subtended at B by AC is 50 degrees. Write the numerical value only, 3 decimal places
