Answer 1

Answer:

thanks for points thanks

Answer 2

• ABCD is a square with side 8 units. •A circle with Centre O and radius R is drawn through a and that is a tangent to BC at e

• Join OD,OA,OE and OF

•AD Is a chord with midpoint F- line of joins center of circle to F hence of perpendicular AD

• In the right angle ODF

OD =r

OF=8-r

OF=AF=4

OD^2 =OF^2+FD^2

r^2=(8-r)^2+5^2

r^2 in quardritic equation is 8r

by simplyfying

r= 9.43 or √89

they fore hence it is not there in given options so none of these option 4

thank you
