Linear Pair Angle 0B3F76

1. **State the problem:** We are given one angle of a linear pair as $120^\circ$ and need to find the measure of the other angle. 2. **Recall the property of a linear pair:** The sum of the measures of two angles forming a linear pair is $180^\circ$ because they are supplementary. 3. **Set up the equation:** Let the measure of the other angle be $x$. Then, $$120^\circ + x = 180^\circ$$ 4. **Solve for $x$:** $$x = 180^\circ - 120^\circ$$ $$x = 60^\circ$$ 5. **Conclusion:** The measure of the other angle in the linear pair is $60^\circ$.
