 07-12-2007 #3 mark r Guest   Posts: n/a Sum of interior angles of a triangle equals 180 degrees.angle1 + angle2 + angle3 = 180angle1 = 70angle2 = 80angle3 = 180 - 80 - 70angle3 = 30answer: a, 30
 07-12-2007 #4 Michael H Guest   Posts: n/a Since the sum of the angles in a triangle equals 180 degreesThe correct answer is180-(70+80)=30
 07-12-2007 #5 Gwenilynd Guest   Posts: n/a In a triangle the angles always add up to equal 180.so 180 - 70 - 80 = 30
 07-12-2007 #6 MensaMan Guest   Posts: n/a If you add up the angles of a triangle you always get 180. So 70 + 80 = 150. Then 180 - 150 = 30. The answer is 30.
