The sum of all angles of a triangle is always 180°.
Let's denote the measure of the third angle as x.
According to the given information, we have:
x + 110° = 180°
We can now solve for x:
x + 110° - 110° = 180° - 110°
x = 70°
Therefore, the measure of the third angle is 70°.
If two angles of a triangle add up to 110°
, what is the measure of the third angle?
