Cos(sin15/17-(sin-5/13)

If sin
=5/13

then the ratio of opposite side/hypotenuse
=5/13
By Pythagorean Theorem
If opposite side =5units and
hypotenuse =13 units

(for any units)
then adjacent side=12 units
and
cos=adjacent side over
hypotenuse =12/13

However, we need to note that if the angle is in Quadrant II then the
adjacent side
will actually be a negative value
so
cos= 12/13 for an angle in Q1
or
cos= -12/13 for an angle in Q2
(angle can’t be in Q3 or Q4, since sin > 0)

What was the reason for temporary imprisonment of certain groups in internment camps during World War II
Scilla [17]
After Pearl Harbor happened for the US in WW II, the US got very scared that there were spies from Japan in the US (It was said that there were spies in Hawaii during Pearl Harbor), so they literally only took Japanese-Americans from the west coast of the US (places like Cali,Oregon,Etc) to places called interment camps, this was just to make sure that none of these people were spies and they couldn't do anything. 
Many of the people taken in these internment camps were US citizens, but if you had one family member with heritage from Japan, you were taken to an internment camp.
