But how
Can you explain clearly
Perpendicular drawn from the centre bisects the chord ...so,it forms 2 triangles take any 1 The perpendicular lenghth is 8 cm & radius
is 17cm then apply Pythagoras theorem
u'll get 15 then double it bcz perpendicular bisects the chord
hence,u get 30
yes you are right
