Answer:

OAC =30

Step-by-step explanation:

Given that for a circle there are two tangents at points of contacts B and C meet at A

The centre of the circle is O.

By tangents theorem for circles, OAB and OAC are congruent

Hence angle OAB = angle OAC

Angle OAB is given to be 30 degrees

Hence angle OAC is equal to 30 degrees
