The ration of the measure of two supplement angles is 7 to 8. Find the measure of each angle.
+781 Supplementary angles add up to 180 degrees. Let x be the number of units so we have 7x and 8x. Then
7x+8x=180
15x=180
x=12
So the two angles are 7(12)=84 and 8(12)=96.
+36916 gs85 has the correct answer....here is another way to solve it
Angle 1 is 7/(7+8) = 7/15 of the total the other angle is 8/15
supplementary angles add to 180o : 7/15 * 180 = 84o 8/15 x 180 = 96o
