Question

If d1, d2 (d2>d1) be the diameters of two concentric circles and c be the length of a chord of a circle which is tangent to the other circle, prove that (d2)2=c2+(d1) 2

Answer 1

given that:

D1 D2 are diameters where did two is greater than the one and and she is length of Chord which is tangent to other circle

to prove:

to prove that a square is equal to C square + D1 square
