Here is my question:
- A circular plate, centre O, has a diameter AOB = 20cm.
- C is a point on the circumference such that angle CAB $= 34^\circ $
- A crack appears along the chord CB and the shaded segment drops off.
Calculate: the length of chord CB
This triangle's base goes across the whole diameter of the circle and is different to the normal chords. This is why I am having trouble with this question.
