Let the measure of the angle be \( x \) degrees. The supplementary angle would then be \( 180 - x \) degrees.
According to the problem, the measure of the angle is thirty-five times the measure of its supplementary angle. We can set up the equation as follows:
\[ x = 35(180 - x) \]
Now, let's solve for \( x \):
- Distribute on the right side:
\[ x = 6300 - 35x \]
- Add \( 35x \) to both sides:
\[ x + 35x = 6300 \]
\[ 36x = 6300 \]
- Divide both sides by 36:
\[ x = \frac{6300}{36} \]
Calculating the division:
\[ x = 175 \]
Now, let's find the measure of the supplementary angle:
\[ 180 - x = 180 - 175 = 5 \]
So, the measures of the angles are:
- The angle is \( 175 \) degrees.
- The supplementary angle is \( 5 \) degrees.
In conclusion, the measure of the angle is \( \boxed{175} \) degrees and the measure of its supplementary angle is \( \boxed{5} \) degrees.
