Algebra.Com's Answer #63766 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Two angles are complementary. One-half the measure of the larger angle exceeds one-fourth the measure of the smaller by 30. Find the measure of the angle, the measure of its supplement and the measure of its complement. \n" ); document.write( "------------------------------- \n" ); document.write( "Let one of the angles be \"x\"; the other is \"90-x\". \n" ); document.write( "EQUATION: \n" ); document.write( "(1/2)x = (1/4)(90-x)+30 \n" ); document.write( "Multiply thru by 4 to get: \n" ); document.write( "2x = (90-x) + 120 \n" ); document.write( "3x = 210 \n" ); document.write( "x = 70 (measure of one of the angles) \n" ); document.write( "90-x = 20 ( measure of the other angle) \n" ); document.write( "=============== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
