You can put this solution on YOUR website! Hi,
*Note: Supplementary Angles have a Sum of 180 degees
.
Let s represent one of the supplementary angles:
The question states the following to be true:
.
Write as you read:
Other angle is (s/2 +12)
.
.
Simplify and Solve for s Angles are 112 and 68 degrees
.
Check You answer:
112 + 112/2 + 12 = 112 + 56 + 12 = 180
You can put this solution on YOUR website! x+x/2+12=180
(2x+x)/2=180-12
3x/2=168 cross multiply.
3x=2*168
3x=336
x=336/3
x=112 answer for the larger angle.
112/2+12=56+12=68 answwer for the smaller angle.
Proof:
112+68=180
180=180
