Final answer:
To prove m∠4 = 62°, you can use the Angle Addition Theorem and the fact that a line is made up of two opposite rays. Here is a complete two-column proof using these concepts.
Step-by-step explanation:
To prove that m∠4 = 62°, you can use the Angle Addition Theorem and the fact that a line is made up of two opposite rays.
Here is a complete two-column proof:
Statement 1: m∠1 = 62°
Statement 2: Given
Reason 1: Given
Statement 3: m∠1 + m∠4 = 180°
Statement 4: Angle Addition Theorem
Reason 2: Definition of a linear pair
Statement 5: 62° + m∠4 = 180°
Statement 6: Substitution
Statement 7: m∠4 = 62°
Statement 8: Subtraction property of equality
Reason 3: Algebraic property
Therefore, it is proven that m∠4 = 62°.
