A triangle has 3 angles of 60 degrees, (5y-40) degrees, and (2y+20) degrees. Show that the triangle is equilateral.

All the angles in a triangle add up to 180 degrees. Therefore, 60 + (5y - 40) + (2y + 20) = 180. This can be simplified to 7y +40 = 180. And simplified again to 7y = 140, which then means y = 140 / 7 = 20 de...
