To determine the measurement of angle \( \angle C \) after it has been rotated \( 19^\circ \) clockwise, we first need to establish the original position of the angle.
Assuming \( \angle C \) is positioned such that one of its rays (or sides) is at the positive x-axis (0°), we can denote the original angle measurement as \( \angle C \). When rotated clockwise, the new angle \( \angle C' \) can be calculated as:
\[ \angle C' = \angle C - 19^\circ \]
If we assume a standard position (like \( \angle C = 0° \)), then after a clockwise rotation of \( 19° \), \( \angle C' \) would simply be:
\[ \angle C' = 0° - 19° = -19° \]
Since angles are often measured in a positive range (0° to 360°), we can convert \( -19° \) to a positive angle by adding \( 360° \):
\[ \angle C' = 360° - 19° = 341° \]
Therefore, if \( \angle C \) starts at \( 0° \) and is rotated \( 19° \) clockwise, the result is:
\[ \angle C' = 341° \]
If you have a different original angle for \( \angle C \), simply replace \( \angle C \) in the calculation with that value, and follow the same steps. Would you like to specify or clarify any details about \( \angle C \) or its initial position?
