if cotx=5/12 anc cosx<0 what is the measure of x to the nearest degeee
\n" ); document.write( "cos function is negative in quadrants II and III.
\n" ); document.write( "cot function is positive in quadrants I and III
\n" ); document.write( "so, in its standard position, the terminal side of x lies in quadrant III.
\n" ); document.write( "Its reference angle =arc cot 5/12=arc tan 12/5=67.38º
\n" ); document.write( "therefore, x=180-67=113º \n" ); document.write( "

\n" );
