Final answer:
Three laws or policies included in the Constitution of 1845 were slavery regulations, taxation policies, and education provisions.
Step-by-step explanation:
Three laws or policies included in the Constitution of 1845 were:
- Slavery regulations: The Constitution of 1845 protected slavery by allowing slaveholding states to count three-fifths of their enslaved population for purposes of representation in Congress.
- Taxation policies: The Constitution addressed taxation by specifying that direct taxes should be apportioned among the states according to their population, including three-fifths of the enslaved population.
- Education provisions: The Constitution did not specifically include education provisions, as education was primarily a responsibility of the states rather than the federal government at that time.
