Question 1174582
<br>
cosine is adjacent over hypotenuse; with the angle in standard position (vertex at the origin), that means cosine is x/r.<br>
So x is 3 and r (radius; hypotenuse) is 5.  The Pythagorean Theorem with the angle in quadrant IV gives us y=-4.<br>
Use the definition of cosecant to answer the question.<br>
