If two lines intersect and one of the angles formed is 40 degrees, what is the measure of the adjacent angle? (2020)

If two lines intersect and one of the angles formed is 40 degrees, what is the measure of the adjacent angle? (2020)

Step 1: Understand that when two lines intersect, they form four angles.
Step 2: Identify that adjacent angles (angles next to each other) are formed by these intersecting lines.
Step 3: Know that adjacent angles are supplementary, which means they add up to 180 degrees.
Step 4: If one angle is given as 40 degrees, write down the equation: Angle 1 + Angle 2 = 180 degrees.
Step 5: Substitute the known angle into the equation: 40 degrees + Angle 2 = 180 degrees.
Step 6: Solve for Angle 2 by subtracting 40 degrees from 180 degrees: Angle 2 = 180 - 40.
Step 7: Calculate the result: Angle 2 = 140 degrees.
