Two men on opposite sides of a TV tower of height h 43 mete

Two men on opposite sides of a TV tower of height h = 43 meters notice the angle of elevation of the top of this tower to be A= 42degree and

distance between 2men AB=AD+DB

tan42^o=43/AD

=>AD=(43/tan42^o)

tan51^o=43/DB

=>DB=(43/tan51^o)

distance between 2men ,AB=(43/tan42^o)+(43/tan51^o)

distance between 2men ,AB=82.577

distance between 2men ,AB=82.6meters
