Algebra.Com's Answer #465906 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! An acute angle θ is in a right triangle with cos θ = five sixths (5/6). What is the value of sec θ? \n" ); document.write( "---- \n" ); document.write( "sec = 1/cos \n" ); document.write( "sec(theta) = 1/(5/6) = 6/5 \n" ); document.write( "---------------------------------\r \n" ); document.write( "\n" ); document.write( "ANd \r \n" ); document.write( "\n" ); document.write( "An acute angle θ is in a right triangle with sin θ = two thirds . What is the value of cot θ? \n" ); document.write( "sin = y/r \n" ); document.write( "--- \n" ); document.write( "If sin(theta) = 2/3, y = 2 and r = 3 \n" ); document.write( "--- \n" ); document.write( "Then x = sqrt[3^2-2^2] = sqrt(5) \n" ); document.write( "---------- \n" ); document.write( "Therefore, cot(theta) = x/y = sqrt(5)/2 \n" ); document.write( "========================================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "================ \n" ); document.write( " \n" ); document.write( " |
