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/...
