In triangle PQR, angle P = angle Q + angle R + 30 degrees. Of all three exterior angles of triangle PQR, what is the least exterior angle, in degrees?

The least exterior angle has to be the greatest interior angle. We know that \(\color{brown}\boxed{\angle{P}}\) is the greatest, because it is greater than the sum of the remaining \(2\) angles.
