(a) Find an angle between 0° and 360° that is coterminal with – 120°.
Novay_Z [31]

Answer:

a)  240\degree

b) \frac{15\pi}{4}

Step-by-step explanation:

<u>Coterminal angles</u> have the same terminal sides in standard position.

a) To find an angle between 0\degree and 360\degree, that is coterminal with -120\degree, we keep adding multiples of 360\degree until we get an angle within the specified range.

 -120\degree \implies -120\degree +360\degree=240\degree.

In some cases you would have to subtract in order to get the specified angle. That is when the angle given is positive.

b) This time we want to find an that coterminal with \frac{15\pi}{4} radians.

We keep subtracting multiples of 2\pi until we get an angle measure within the specified range.

\frac{15\pi}{4}=\frac{15\pi}{4}-2\pi=\frac{7\pi}{4}

Who failed to support civil rights for freed slaves? (wrong category by mistake, not mathematics)
dangina [55]

Answer:

The Supreme Court.

Step-by-step explanation:

After the end of the Civil War and the enactment of the Thirteenth Amendment in 1865, slavery was officially abolished in the United States. Thus, the millions of African American slaves that inhabited the southern states of the country won their freedom and equality before the law against whites.

Now this situation began to dismember in 1877, when federal troops left the southern states and Reconstruction officially came to an end. From then on, Democratic governors and legislators began to sanction the Black Codes and Jim Crow Laws, aimed at curtailing the civil and political rights of African-Americans.

This situation was tested before the Supreme Court in 1896 in the case Plessy v. Ferguson. But in the ruling of said case, the Supreme Court established that racial segregation was constitutional and therefore neglected African Americans and their rights.
