first          x
second         y
third          y+18
sentence2      y+(y+18)=2x      
SUM           x+y+(y+18)=180

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is twice the measure of the first angle. The third angle is eighteen more than the second. Find the measures (in degrees) of the three angles.
Angles are NOT 70o, 51o, and 59o, as reported by the other person!
