Question 1112428
.

The correct answer is 


{{{csc(theta)}}} = {{{1/sin(theta)}}} = {{{13/5}}}.


<pre>
The problem does not ask about the value of {{{theta}}}, but the other tutor for some (unknown to me) reason gives the value of  {{{theta}}}  as the answer, 


and makes it  <U>I N C O R R E C T L Y</U>.


The correct value of {{{theta}}} (although, again, the problem does not ask about it !) is {{{theta}}} = {{{pi - arcsin(5/13)}}} = 180 - 22.62 = 157.38 degrees.
