Answer:

c = 0.5 cm

Step-by-step explanation:

Using the Sine rule in the triangle, then

$\frac{c}{sin15}$ = $\frac{2}{sin105}$ ( cross- multiply )

c × sin105° = 2 × sin15° ( divide both sides by sin105°

c = $\frac{2sin15}{sin105}$ ≈ 0.5 cm ( to the nearest tenth )

What can those engaged in politics from both parties learn about the Constitution from the debate over the Bill of Rights?

morpeh [17]

Answer:

The Federalists wanted a strong government and strong executive branch, while the anti-Federalists wanted a weaker central government. The Federalists did not want a bill of rights —they thought the new constitution was sufficient. The anti-federalists demanded a bill of rights.

Federalists argued that the Constitution did not need a bill of rights, because the people and the states kept any powers not given to the federal government. Anti-Federalists held that a bill of rights was necessary to safeguard individual liberty.
