Final answer:
To prove that m<4 = 62°, use the Vertical Angles Theorem and the given information. Since m<1 = 62° and lines t and l intersect, the vertical angles formed are congruent, so m<4 = 62°.
Step-by-step explanation:
To prove that m<4 = 62°, we can use the Vertical Angles Theorem. This theorem states that when two lines intersect, the vertical angles formed are congruent. In this case, m<1 and m<4 are vertical angles. Since m<1 = 62°, we can conclude that m<4 = 62° as well.
Therefore, the proof can be constructed as follows:
