Two ships X and Y are sailing away from a glacier in the same direction. If the height of the glacier is 1000 m and the angle of elevation made by the 2 ships are 45 and 30 degree respectively, then what is the distance between the two ships?

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
