Question

in the figure find the length of the tangent CD if a b is equal to 3 cm and BC is equal to 8 cm​

Answer 1

the answer is 5cm

ap and bp are tangents extended from same point

so ap=bp

bp=3cm

BC=pc-bp

BC=8-3

BC=5cm
and cd and bd are also tangents extended from the same point
so BC=CD
so CD=5cm

Answer 2

Thank you for asking this question. Here is your answer:

CD = BC

= 3 cm

BC = 8 cm  

CD = PB +BC

8 = 3 + BC

BC = 5

BC = CD

So CD will be 5 cm
