Question 704108: In a triangle, the first angle is 10 degrees smaller than the second angle. The third angle is three times as large as the first angle. What are the sizes of angles? Answer by rfer(16322) (Show Source):
You can put this solution on YOUR website! 1) x-10=34
2) x=44
3) 3(x-10)=102
----------------
x-10+x+3x-30=180
5x=180+40
5x=220
x=220/5
x=44
x-10=34
3(x-10)=102
