If two angles are supplementary then the sum of the two angles in 180 degrees The measure of one angle is three times the measure of another Write a math sentence to represent this situation and find the measure of each angle

Let "n" represent an unknown number:

n + 3n = 180

To solve this equation we would add like terms, which is 1+3 which gives us 4n. Now that we know that we can divide 180 by 4 to find that n is equal to 45, meaning that the math sentence becomes 45 + 135 = 180.
