<PRE><B>Question 1110369</B>
Find the measure of an angle such that the difference between the measures of its supplement and three times its complement is 40°. 
-------
Angle:: x
supplement:: 180-x
complement:: 90-x
---
Equation::
180-x -3(90-x) = 40
180-x -270+3x = 40
2x -90 = 40
2x = 130
x = 65 degrees
