If a pentagon has one angle measuring 120 degrees, what can be inferred about the other angles?

If a pentagon has one angle measuring 120 degrees, what can be inferred about the other angles?

Step 1: Understand that a pentagon has five sides and five angles.
Step 2: Know that the sum of all interior angles in a pentagon is 540 degrees.
Step 3: Identify that one angle of the pentagon is given as 120 degrees.
Step 4: To find the sum of the other four angles, subtract the given angle from the total sum: 540 degrees - 120 degrees.
Step 5: Calculate the result: 540 - 120 = 420 degrees.
Step 6: Conclude that the sum of the other four angles in the pentagon is 420 degrees.
