To find the measure of the third angle in a triangle when two angles add up to a certain value, you need to subtract the sum of the two given angles from 180°.
In this case, if two angles of the triangle add up to 110°, then the measure of the third angle can be found by subtracting 110° from 180°:
180° - 110° = 70°
Therefore, the measure of the third angle in the triangle is 70°.
If two angles of a triangle add up to 110° what is the measure of the third angle?
