We are asked to find the size of angle $r$. We are given two angles: $47^\circ$ and $16^\circ$.

1. Problem Description

We are asked to find the size of angle $r$. We are given two angles: $47^\circ$ and $16^\circ$.

2. Solution Steps

The angles $47^\circ$ and $16^\circ$ are adjacent angles.

The sum of the adjacent angles which are vertically opposite to $r$, is equal to $47^\circ + 16^\circ$.

The vertical angles are congruent, that is, they have the same measure.

So, the angle vertically opposite to $r$ is equal to $47^\circ + 16^\circ$.

Therefore, the angle $r$ is vertically opposite to an angle that measures $47^\circ + 16^\circ$.

$r = 47^\circ + 16^\circ$

$r = 63^\circ$

3. Final Answer

The size of angle $r$ is $63^\circ$.
