If the angles of elevation of a pole from two points located in the same direction at distances of x and y (x > y) from its foot are 30 and 60 degree, then what will be the height of this pole?

Heights and Distances problems on: Applications of right triangles in geometry, including problems involving height and distance, angle of elevation, angle of depression, and multiple observers. Trigonometric ratios can be used to find heights and distances.  Here are some formulas related to height and distance:  Height: height=tan(angle) x  distance Distance: $B (distance)= A (height)tan (e )    Some other useful heights & distance formulas are:  sin = height/ hypotenuse  cosec = hypotenuse/ height  cos = distance/ hypotenuse  sec = hypotenuse/ distance  cot = distance/...

Trigonometric ratios can be used to find heights and distances. 
Here are some formulas related to height and distance: 

Height: height=tan(angle) x  distance

Distance: $B (distance)= A (height)tan (e )   

Some other useful heights & distance formulas are: 
sin = height/ hypotenuse 
cosec = hypotenuse/ height 
cos = distance/ hypotenuse 
sec = hypotenuse/ distance 
cot = distance/ height 
tan = height/ distance 
sin^2 θ + cos^2 θ = 1 
1 + tan^2 θ = sec^2 θ
