If two secants are drawn from a point lying outside a circle, then the product of one secant on its outer part is equal to the product of the other secant on its outer part. DE*CE = AE*BE DE = CD + CE = 1 + x + 4 = x + 5 AE = AB + BE = 11 + x + 1 = x + 12 (x+5)(x+4)=(x+12)(x+1) x² + 4x + 5x + 20 = x² + x + 12x + 12 9x + 20 = 13x + 12 20 - 12 = 13x - 9x 8 = 4x x = 8/4 x = 2
