we need to find the sides by using simple theorems like the lengths of two tangents from an external point to a circle are equal.
I used that but was not able to get the full length of AB and AC..
I am having maths exam tomorrow, pls help soon.

a triangle ABC is drawn to circumscribe a circle of radius 4 cm such that the segments BD and DC into which BC is divided by the point of contact D are of lengths 8 cm and 6cm respectively. find the sides AB and AC.

If he didn't speak english, then what's the use of inventing a TM and then going back to find a Greek book which I won't be able to even read.
Let's drop that idea and use that pdf (which is a much better option) and be happy.

In book 3, proposition 18, of Euclid's Elements, he tackles this very problem. You'll be pleased to know, he does it by contradiction!
where can we find that book?
