Answer:
CD=5cm
Step-by-step explanation:
given,
AP=3cm
PC=8cm
AP=BP (tangents drawn from an external point)
BP=3cm (putting in the values)
now,
PC= BP + BC
8=3+BC (putting in the values)
BC=5cm
BC=CD (tangents drawn from an external point)
CD=5cm. (putting in the values)

even starting also
i sent
the sum of first 8 term of an ap is hundred and sum of first night in term is 551 find a AP
I didn't understand the first one
but the second one
using the sum of AP formula and taking Sn as 100 and n as 8 u will get a equation
similarly take the 9th term and get a equation
now using elimination or substitution find a and d
then u can form a Ap
ok

Thank you for asking this question. Here is your answer:
AP = PB
= 3 cm
PC = 8 cm
PC = PB +BC
8 = 3 + BC
BC = 5
BC = CD
So CD will be 5 cm
If there is any confusion please leave a comment below.
Thanks
