(Score for Question 2 of 5 points) 2. Jacque estimates the square root of 125 in the following way V125 = 525 = 5 * 5 = 25 (a) Explain why his reasoning is incorrect. (b) Approximatee the square root of 125 using the perfect squares approximation method. Your answer should be a mixed fraction Make sure to show your work a. Note: If you're using the perfect squares approximation method your answer should be a mixed fraction. Please review 5.05 if you need a place to start​

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
