height the building must be raised by 73 m so that it's angle of elevation from the same point be 60 degree
Step-by-step explanation:
let AB be the tower and P be the point of observation making an angle of elevation 45°
let BC be the raised height so that the angle of elevation be 60°
in triangle APB
AB = 100 m
in triangle APC
putting the value of √3 = 1.73
100(0.73) = x
73 = x
BC = 73 m
hence ,
height the building must be raised by 73 m so that it's angke of elevation from the same point be 60 degree
