Question

plzz solve it_______/__

Answer 1

let the height of the tower be x

and flagstuff be m

now in triangle abc

tan45=bc/ab

1=h/70

h=70

in triangle abd,

tan60=dc+bc/ab

√3=x+70/70

x+70=70√3

x=70√3-70

x=70[√3-1]

x=51.24m

the height of the flag is 51.24m

the height of the tower is 70m
