If the angle of the elevation of the top of a chimney from a point om the horizontal plane passing through the foot of the chimney id 60 ° and the angle of elevation from another point ion the same plane at a distance of 24 meters from the first point is 30 °, let us write by calculating the height of the chimney. [ Let us find the approximate value correct up to three decimal places, assuming [√3 = 1.732 approx.]
