Suppose a plane coming down for a landing at an airport. The angle of depression is 22 degrees. The plane is 350m from the landi

Nostrana [21]

See attached diagram.
A right triangle is formed with the 350m adjacent to the 22° angle.
We want to find the height of the triangle, the side opposite.
We can use the tangent ratio (opposite/adjacent) to find this height.
tan(22°) = x/350
Multiply each side by 350
350tan(22°) = x ≈ 141.4 m
