A circular mirror with radius 27cm hangs from a hook. The wire is 46cm long and is a tangent to the circle at points A and B. How far, to the nearest tenth, above the top of the mirror is the hook? A B and O form a triangle from point O to B it is 27cm as well as O to A. A B and T also form a triangle from point A to T it is 23cm as well as B to T A B O T form a quadrilateral (My question) How far, to the nearest tenth, above the top of the mirror is the hook?
