In a triangle, the sum of all three interior angles is always 180 degrees. If two angles add up to 110 degrees, you can find the measure of the third angle by subtracting the sum of the two angles from 180 degrees.
Let the two angles be \(A\) and \(B\): \[ A + B = 110^\circ \]
To find the third angle \(C\): \[ C = 180^\circ - (A + B) \]
Substituting the sum of the two angles: \[ C = 180^\circ - 110^\circ = 70^\circ \]
Therefore, the measurement of the third angle is \(70\) degrees.
