Mrs. Pumphrey was a rich lady who had a small pet dog named Tricki. She was foolishly indulgent and would pamper the dog by giving him chocolates, cakes, juice, eggs and wine. She was ignorant and did not know that the dog needed exercise also. So when he fell sick she was very anxious and thought that something very serious had happened to him. She was silly but tender hearted. She cried bitterly when Tricki was taken to the hospital. She was a simple person and it was easy to please her. She was happy when her pet became alright. She was grateful to Dr. Harriot for making Tricki healthy. She went to the extent of calling it a 'Triumph of Surgery'. So we can say that Mrs. Pumphrey was a rich, foolishly indulgent, ignorant, anxious, silly, tender hearted, simple, easy to please, and a grateful person.

(5+√23) (8-√23)
= 5 (8-√23) + √23 (8-√23)
= 5 (8) - 5 √23 + 8 √23 - √23(√23)
= 40 +(-5 + 8)√23 - 23
= 17 + 3√23

Since, length of two tangents drawn from an external point of circle are equal.
So, AP = AS
BP = BQ DR = DS
and RC = CQ
Adding all, we get
(AP + BP) + (DR + RC) = AS + BQ + DS + CQ
⇒ (AP + BP) + (DR + RC)
= (AS + DS) + (BQ + CQ)
⇒ AB + DC = AD + BC
⇒ 6 + 4 = AD + 7
⇒ 10 = AD + 7
AD = 10 – 7 = 3 cm
Hence, AD = 3 cm.
