Q 1730134912.     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
mid-point of `QR`. Let `CD` be another chord of this
circle passing through `P` such that `angleCPQ` is acute.
If `M` is the mid-point of `CD` and `MP` `= sqrt24` cm,
then which of the following statements are correct `?`

1. `angleQPD = 135^0`

2. If `CP = m` cm and `PD = n` cm, then `m` and `n` are the
roots of the quadratic equation `x^2-10x +1 =0`.

3. The ratio of the area of `DeltaOPR` to the area of
`DeltaOMP` is `1 : 2sqrt2`
.
