We have been given a diagram and we need to find the value of arc angle a.

According to one of the circle theorems the angle at the centre of a circle is twice the angle at  the circumference subtended by the same arc.

Therefore, arc angle a will be twice of the angle at circumference, that is, 34 degrees.

Therefore, value of angle a is:
