Question

in the given figure,PQ=8cm and A is mid point of PQ,find AB. plz it's very urgent plz. quickly............ answer

Answer 1

Answer:

AB = 4cm

Step-by-step explanation:

It is given that ,PQ=8cm and A is mid point of PQ,find AB.

Therefore AP = AQ = 8/2 = 4 cm

From the figure we get,

AP = AB (Because AP and PB be the two tangent of the first circle from a common point A)

Similarly AB = AQ (Because AB and AQ be the two tangent of the first circle from a common point A)

Therefore , Ap = AB = AQ = 4cm

Answer 2

Answer:

Step-by-step explanation:

Concept:

The two tangents drawn from an external point to a circle are equal in length.

Hence AQ=AP=AB

But A is the midpoint of PQ

AQ=PQ/2 = 8/2 =4cm

Therefore AB= 4cm

I hope this answer helps you
