in a circle of radius 6cm , a chord is drawn 3cm from the circle (a)calculate the angle subtended by the chord at the centre of the circle

Answer 1

so your chord is also 3 cm from the centre.

construct the right-angles triangle
look at the angle it makes at the centre,
cosØ = 3/6 = 1/2
Ø = 60°

the chord subtends an angle of 120°
