A flag staff PN stands upright on a level ground. A base AB is measured at right. Angle to AN such that points A,B,N lie in the same horizontal plane. If `anglePAN=alpha and anglePBN=beta`, then height of flag staff is _____.

AB is a vertical pole resting at the end A on the level ground. P is a point on the level ground such that AP = 3AB and C Is the midpoint of AB. If AC and CB subtend angles alpha and beta , respectively, at P, then the value of tan beta is

A flagstaff stands on the top of a vertical tower. It is found that the flagstaff subtends the same angle alpha at two points , 2d apart, on a straight line through the base of the tower on the horizontal plane. Also the flagstaff subtends an angle beta at the midpoint of these two points find the value of

If a flag staff subtends the same angles at the points A,B,C and D on the horizontal plane through its foot, the points A,B,C and D from a

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 ?
