If angle θ is a principal angle that lies in quadrant 3 such that 0° ≤ θ≤ 360°, determine the exact values of x, y, and r for tan θ =2/3
\n" ); document.write( "-----------
\n" ); document.write( "tan is + in Q3
\n" ); document.write( "tan = y/x
\n" ); document.write( "tan = -3/-2
\n" ); document.write( "--> x = -3, y = -2
\n" ); document.write( " $\"r+=+sqrt%28x%5E2+%2B+y%5E2%29+=+sqrt%2813%29\"$
\n" ); document.write( " \n" ); document.write( "
