Question

 In the given figure, O is the centre of the circle and AB is parallel to CD. AB = 24 cm and the distance between the chord AB and CD is 17 cm. If the radius of the circle is 13 cm, the length of the chord CD is:​

Answer 1

Step-by-step explanation:

The chord line form centre of the circle bisect the chord equally. T, therefore, AM = 12 , nowhsbjdbd in triangle AOM now , OM = 169 -144 = √25 = 5 ,ON = 5 no w in triangle CON CN = 13^2 - 25^2 = 144

CN = 12 , therefore CD = 24
