Answer» sorry the picture is not clear hope u got the answer! Answer: Step-by-step explanation: let height of tower = x + 10m let dist. between base of tower and obs. pt. = y at first angle it makes with ground = 60 degree tan(60) = sqrt{3} = (x + 10)/y . . . . . . (eq 1) next angle = 45 degree pt is 10 m above the ground tan(45)= 1 = x/y :. x=y . . . . . . . . . (eq. 2) substituting value of y in eq. 1 x + 10 = 1.732 x :. x = 13.66

sorry the picture is not clear

Answer:

Step-by-step explanation:

let height of tower = x + 10m

let dist. between base of tower and obs. pt. = y

at first angle it makes with ground = 60 degree

tan(60) = sqrt{3} = (x + 10)/y . . . . . . (eq 1)

next angle = 45 degree

pt is 10 m above the ground

tan(45)= 1 = x/y

:. x=y . . . . . . . . . (eq. 2)

substituting value of y in eq. 1

x + 10 = 1.732 x

:. x = 13.66
