The sum of the measures of two angles is 183.6°. One angle has a measure of 54°. What is m , the measure in degrees of the second angle?
m = 3.4°
m = 129.6°
m = 9,914.4°
m = 237.6°
m = 129.6°
To find the measure of the second angle, subtract the measure of the given angle from the sum of the measures of the two angles.
m = (Sum of the measures of the two angles) - (Measure of the given angle)
m = 183.6° - 54°
m = 129.6°
Therefore, the measure of the second angle is 129.6°.
So, the correct answer is m = 129.6°.
