Question 513394: How do you do this problem?
You're supposed to find the third angle of the triangle.
y degrees, 110 degrees, __________
Answer by umail08(87) (Show Source): You can put this solution on YOUR website!
The sum of the angles of a triangle is 180 degrees, so:
Let Angle A = y degrees, Angle B = 110 degrees, Angle C = unknown
Angle A + angle B + Angle C = 180 degrees
Y + 110 + Angle C = 180 degrees
Angle C = 180 � y � 110
Angle C = 70 � y
