Hi, I have a question, according to the diagram shown below,
what is if the slope is known, (such as ). How do we find slope if we know ?
Note: Figure is not drawn to scale.
The "slope" of a line is the tangent of the angle, , so the angle is the inverse tangent:
I don't understand the "vice-versa" part of your question. Your original question was "how do I find the angle" so "vice-versa" would be "how does the angle find me"!
