Algebra.Com's Answer #652522 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! The sine is opposite over hypotenuse or -8/9 \n" ); document.write( "The other side must be the square root (17), so that the sum of the squares of the legs=square (hypotenuse) \n" ); document.write( "That makes the cosine= +square root (17)/9, so the secant is 9*square root (17)/17, the reciprocal, after rationalization of the denominator.\r \n" ); document.write( "\n" ); document.write( "The cotangent is cosine/sine, or sqrt(17)/9/-8/9, or - sqrt(17/8). \n" ); document.write( " |
