You will need this formula to work out one of the angles and then the other angles can be calculated.
Each Angle (of a Regular Polygon) = (n-2) × 180° / n

Use the formula for the interior angles of a regular polygon, (x-2)180/x. You then know that as it is a regular 12-sided polygon, PQ = QR, so the triangle is an isosceles, hence angle PRQ = (180- PQR)/2.
