The sum of the three angles of a triangle is always 180°.
If two angles of a triangle add up to 110°, then the sum of the three angles can be expressed as:
110° + Third Angle = 180°
Subtracting 110° from both sides we get:
Third Angle = 180° - 110°
Third Angle = 70°
Therefore, the measure of the third angle is 70°.
If two angles of a triangle add up 110° , what is the measure of the third angle?
