Answer 1

Answer:

At one end of diameter AB of a circle of radius 13 cm, tangents XAY is drawn to the circle. The length of the chord CD parallel t XY and at a distance 18 cm from A is

Answer 2

Answer:

CD is parallel to XY

OA and OE are perpendicular to XAY and CED respectively

<OAY=90°=<OED

<OED + <OEC = 180° [supplementary angle]

<OEC = 90°

Hence OEC is right ∆

radius = 13 cm

OA = OC =13 cm[ radii of the circle]

AE = 18cm

OE = 18-13= 5cm

EC = √13^2-5^2[Pythagoras theorem]

EC=12cm

Chord DC=12×2=24cm

ans is 24 cm
