A vertical tower stands on a horizontal plane and is surmounted by a flag-staff of height 7m. From a point on the plane, the angle of elevation of the bottom of the flag-staff is `30o` and that of the top of the flag-staff is `45o` . Find the height of the tower.

A vertical tower stands on a horizontal plane and is surmounted by a vertical flag staff of height h. At a point on the plane, the angle of elevation of the bottom of the flag staff is alpha and that of the top of the flag staff is beta . then the height of the tower is एक ऊर्ध्वाधर मीनार एक क्षेतिज समतल पर खड़ी है और उसके ऊपर 1 ऊँचाई का ऊर्ध्वाधर ध्वजखण्ड लगा है। समतल पर एक बिन्दु पर ध्वजदण्ड के तल का उन्नयन कोण alpha है और ध्वजदण्ड के शीर्ष भाग का beta है। मीनार की ऊँचाई बताइए ?
