Question

In the given figure, AOB is a diameter and DC is parallel to AB. If ∠CAB = x°; find (in terms of x) the values of ;
∠COB,

Solution

∠COB = 2 ∠CAB = 2x

(Angle ate the centre is double the angler at the circumference subtended by the same order)

  Is there an error in this question or solution?
