Polar coordinates are a way to describe where a point is on a plane. Instead of using x and y, you use the angle theta and radius r, to describe the angle and distance of the point from the origin.
The point \((5, 5\sqrt{3})\) in Cartesian coordinates can be expressed as \((r, \theta^{\circ})\) in polar coordinates, where \(r\) is a positive real number and \(0 \leq \theta \leq 180\). What is the value of \(r+ \theta\)?

The point \((-21\sqrt{3}, 21)\) in Cartesian coordinates can be expressed as \((r, \theta)\) in polar coordinates, where r is a positive real number and \(0^{\circ} \leq \theta \leq 180^{\circ}\). If \(\theta\) is measured in degrees, what is the value of \(r+ \theta\)?
