Answer :
The measure of the supplementary angle is 7°.
Angles that add up to 180° are referred to as supplementary angles. For instance, angle 130° and angle 50° are supplementary angles as the total of these two angles is 180°. The sum of complementary angles is 90°.
Given that the measure of the angle is 173°
Let the supplementary angle = x
Then the sum of this angle and x will be equal to 180°.
So, to find x:
173 + x = 180
x = 180 - 173
x = 7°
Therefore, the measure of the supplementary angle is 7°.
