Hi Friends,
I am getting problem in a geometry problem. Please help me to find the answer.
The problem is as follows:
AB, BC, CD, AD are the tangent of circle of radius 10 cm. and center O. If the length of BC = 38 cm and CD = 27 cm. Then find the length of AB. Here tangent AB and AD are perpendicular to each other.

ATTEMPT :
Here AP=AQ
&
OP = OQ = 10 cm
∵ ∠ PAQ = 90°
∴ quadrilateral AQOP will be a square
∴ AQ = AP = 10 cm
Now, BQ = (x - 10)
Now, BQ = BR = (x-10)
So, CR = (11 + x) = CS
Now, SD = (16 - x) = DP
…….
But after this I am unable to complete this. The answer which the book is showing is,
x = 21 cm.
Please friends help me in finding out the answer. Thank you all in advance.
