from a certain spot, the top of a triangle had an angle of elevation of 40 degree. move 15meter in a straight line towards the flag pole.Now to the top has an angle of elevation of 60degree.Find the height of the flagpole and it's distance from the second point.

Answer 1

If the distance on the ground is x, and the height of the pole is h,

h cot40° - h cot60° = 15
x/h = cot60°
