Question

the radii of two concentric circles are 13 cm and 8 cm. ab is a diameter of the bigger circle and BD is a tangent to the smaller circle touching it at D and intersecting the larger circle at P on producing. find the length of AP​

Answer 1

Answer:

Step-by-step explanation:

Both the circles have same centre as A

AB=13 (given)

The tangent to the smaller circle touches at point D

AD=8-radii

Ad is perpendicular to BD as tangent is perpendicular to radius

So AP is hypotemus triangle ADP
