It seems like you're looking for the value of \( c \) where \( c \) is the measure of an angle. The equations you've provided are:
- \( 63^\circ \)
- \( (7c)^\circ \)
It's unclear from the question how these two angles are related.
If we're assuming that these angles are equal to each other, we can set up the equation:
\[ 7c = 63 \]
To solve for \( c \), we can divide both sides by 7:
\[ c = \frac{63}{7} = 9 \]
So, the value of \( c \) is \( 9^\circ \). If you meant something different or if the context was different, please provide more details!
