A triangle has its three angles in arithmetic progression. If the smallest is 10degrees find the other two angles
10+x+y=180
the only way i know how to do this is guess and check, giving me:
x=60
y=110
this way they progress arithmetically and the common difference is 50

If the first angle is 10, then the second angle is 10+d and the third is 10+2d where d is the common difference.
Then 10+10+d+10+2d=180
d = 50
So the angles are 10, 10+50=60, 10+2(50)=110
I guess the math tags have trouble with the new server
