Question

when we viewed top of a tawer of height 100 meter the angle of elivation of boat30 degree the boat moves x meter towards tower and angle of elevation changed to 5 degree find value of x​

Answer 1

Answer:

x=(100√3) - (100/tan35)

Step-by-step explanation:

let y be the initial distance from the boat

so y=100/tan30

let z be the new distance of the boat from he tower

z=100/tan35  ; ( increase in 5 degree angle )

so,

  x=y-z
