The measure of an angle is 159°. What is the measure of its supplementary angle?
two supplementary angles add to 180°, right?
so what is 180-159 ?
The supplementary angle of an angle is the angle that when added to the given angle, sums up to 180°. To find the measure of the supplementary angle, subtract the measure of the given angle from 180°.
180° - 159° = 21°
Therefore, the measure of the supplementary angle is 21°.
To find the measure of the supplementary angle, we need to know that supplementary angles are two angles whose measures add up to 180 degrees.
Given that the measure of one angle is 159 degrees, we can subtract this measure from 180 degrees to find the measure of the supplementary angle.
Let's calculate it:
180 degrees - 159 degrees = 21 degrees
Therefore, the measure of the supplementary angle is 21 degrees.
