Is the point 3/5 and 4/5 corresponds to an angle in the unit circle what is the csc

csc = 5/4

Step-by-step explanation:

Assuming that the two given points 3/5 and 4/5 are the two sides of a triangle and a right angle 0  with legs x and y and z as its hypotenuse.

Then using Pythagoras Theorem:

Taking square root on both the sides:

Now,

and we know that

Therefore, csc = 5/4.

To tell whether r = 2 is a solution of the inequality, substitute 2 for r and see whether the inequality produces a true or a false statement.

(2) + 4 > 8, add 2 and 4.

6 > 8, this is a false statement, because 6 is not greater than 8, so the value r = 2 is not a solution of the inequality r + 4 > 8.
