Answer 1

Answer:

AD=7.4cm

I may think u can get the answer by this.

Good luck for every one dude.

Answer 2

Answer:

3 cm

Step-by-step explanation:

AS and AP are tangents drawn from A to the circle

⟹AS=AP

Similarly

DS=DR, RC=CQ, QB=BP

AB= AP+PB = 6

AP= 6−PB

BC=  BQ+QC =  7 cm

CD=  CR+DR  = 4 cm

AD= AS+SD = AP+RD

= (6−PB )+ (4−CR)

= 10–(PB+CR)

= 10– (BQ+CQ )= 10−BC

= 10–7

= 3 cm
