Calculate distance from a point 100m from a plane given two angles

[robertadamplant]

I am looking for a formula.

From a horizontal plane of 100 meters; If angle on the left is 8 degrees and the angle on the right is 21 degrees at what distance from the centre of the horizontal plane will these two angles converge?

Your question above does not contain enough information for an answer. We will need more parameters to provide any meaningful answer.

This is not differential geometry.

There is no such thing as a 'plane of 100 metres', and planes do not have a centre.

I think the question you meant to ask is "a triangle has a base of 100 metres and sides at angles 8 degrees and 21 degrees from the base; what is the height of the triangle?". If this is not what you meant or you are unsure, draw a diagram.

And @robertadamplant -- is this a schoolwork question?
