Acompany that makes mirrors sends their slightly flawed products to a discount store. this week, the company sent four mirrors to the discount store. for each mirror, both lengths and widths are the same, but their angle measures vary slightly. mirror 1 length: 16 inches width: 18 inches diagonal: 25 inches mirror 2 length: 16 inches width: 18 inches diagonal: 26 inches mirror 3 length: 16 inches width: 18 inches diagonal: 23 feet mirror 4 length: 16 inches width: 18 inches diagonal: 24 inches based on these dimensions, which mirror is the closest to rectangular?

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
