Question 558216: An angle is 5 degrees less than twice another angle. Find the measures if they are supplementary angles.
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! Let x = one of the angles
2x-5 = second angle
Supplementary means that the angles add to 180 degrees.
x + 2x-5=180
3x - 5=180
3x=185
x=185/3=61.666...
2x-5=370/3-5=123.333...-5=118.333...
Check: 61.666... + 118.333... = 180 It checks!!
