Thread: Angle between circle and tangent

Dear Forum members,


If radius R of the circle and the tangent length L are known, how could we calculate the angle (Theta) between the circle and the tanget?


Thank you very much for the help!

best regards

Raj

Hi Raj,

There is an error in the figure you have attached the reference of as represented by an arc is a mistake it complicates things. I have modified the figure I hope this is what you intended to ask.

In the figure attached the angle suptended at the circumference is (by alternate segment theorem). So we have =
