A figure is shown, where x represents the measure of an unknown angle.
154⁰, 70⁰, x⁰
What is the measure of the unknown angle?
The measure of the unknown angle can be found by subtracting the sum of the given angles from 180°.
Sum of given angles = 154° + 70° = 224°
180° - 224° = -44°
Therefore, the measure of the unknown angle is -44°.
