Algebra.Com's Answer #551519 by stanbon(75887) ![]() You can put this solution on YOUR website! The sin (angle)=15/17. Determine the exact value of the other two ratios,if angle is in II quadrant \n" ); document.write( "------ \n" ); document.write( "Note: x is negative in QII \n" ); document.write( "----- \n" ); document.write( "By definition, sin = y/r \n" ); document.write( "Since sin = 15/17, y = 15 and r = 17 \n" ); document.write( "--- \n" ); document.write( "Then x = -sqrt[17^2-15^2] = -sqrt(64) = -8 \n" ); document.write( "----- \n" ); document.write( "Ans: \n" ); document.write( "sin = y/r = 15/17 \n" ); document.write( "cos = x/r = -8/17 \n" ); document.write( "tan = y/x = -15/8 \n" ); document.write( "------------------------ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
