Question 151515
Let x=measure of supplement angle


Supplemental angles add up to 180 degrees. So that means that {{{55+x=180}}}



{{{55+x=180}}} Start with the given equation.



{{{x=180-55}}} Subtract {{{55}}} from both sides.



{{{x=125}}} Combine like terms on the right side.

Answer:


So the answer is {{{x=125}}} which means that the measure of the supplement angle is 125 degrees
