60 degrees

As the ratio of the two angles is 3:6, the smaller angle would be
3/(3+6) or 3/9 or 1/3. The sum of two supplementary angles is 180*, and so the smaller angle would be 1/3 of 180*, i.e. 60*.

x/y = 3/6
x+y = 180
=>
x = 3y/6
x+y = 180
=>
3y/6+y = 180
3y+6y = 1080
9y = 1080
y = 120
=>
x+120 = 180
x = 60
Answer: the measure of the smaller angle is 60º.

3x + 6x = 180
9x = 180
x = 20
3x = 60
The smaller angle is 60 degrees.
(The larger angle is 120 degrees.)

3/(3+6)=x/180*
3/9=x/180*
9x=540*
x=60*

supplementary means they add up to 180. 3x+6x = 180. solve from their, and be sure to plug back in your answer for x to "3x"
