  • Answer

Let ABCDA B C D be a rectangle and EE be a point on segment ADA D. We are given that quadrilateral BCDEB C D E has an inscribed circle ω1\omega_{1} that is tangent to BEB E at TT. If the incircle ω2\omega_{2} of ABEA B E is also tangent to BEB E at TT, then find the ratio of the radius of ω1\omega_{1} to the radius of ω2\omega_{2}.
