Consider a circle with centre at O and radius 7 cm. Let QR be a chord of length 2 cm and let P be the midpoint of QR. Let CD be another chord of this circle passing through P such that ∠CPQ is acute. If M is the midpoint of CD and MP = √ 24 cm, then which of the following statements are correct?
1. ∠QPD = 135°
2. If CP = m cm and PD = n cm, then m and n are the roots of the quadratic equationx 2 − 10 x + 1 = 0.
