Question 1112428: find csc 0 if 0 is an angle in standard position whose terminal side passes through (-12, 5) Found 2 solutions by stanbon, ikleyn:Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! find csc 0 if 0 is an angle in standard position whose terminal side passes through (-12, 5)
-----
csc = 1/sin = r/y
r = sqrt[12^2+5^2] = sqrt[144+25] = sqrt(169) = 13
====
csc(t) = 13/5
---
Ans: Theta = arcsin(5/13) = 22.62 degrees

The problem does not ask about the value of , but the other tutor for some (unknown to me) reason gives the value of as the answer,
and makes it I N C O R R E C T L Y.
The correct value of (although, again, the problem does not ask about it !) is = = 180 - 22.62 = 157.38 degrees.
