Answer:
7cm
Step-by-step explanation:
Use the property that if circle is inscribed in a quad. then sum of opposite sides is equal (u can prove it by the fact that a point outside circle has 2 tangents of equal length on a circle)
now AB + CD = BC + AD
5 + 8 = 6 + AD
AD = 7cm

And is 3
Ans is 3
That is wrong and or a little mistake in question because if you see AB + BC = 11 and CD = 8 cm now if u subtract u get 3cm but it is not true.
I insist you to recheck the question
If ans is 3 then BC must be 8cm and CD must be 6cm but in the question opposite is mentioned
