Algebra.Com's Answer #180876 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! The two angles are complementary. The sum of the measure of the first angle and 1/4 of the second angle is 75 degrees. Find the measures of the angles. \n" ); document.write( ": \n" ); document.write( "When two angles are complimentary, that just means that they add up to 90 degrees \n" ); document.write( ": \n" ); document.write( "Let x = an angle (the first angle) \n" ); document.write( "Then \n" ); document.write( "(90-x) = the other angle (second angle) \n" ); document.write( ": \n" ); document.write( "When it says,\"The sum of the measure of the first angle and 1/4 of the second angle is 75 degrees.\" we can write this \n" ); document.write( "x + \n" ); document.write( "solve this for x and we have one of the angles \n" ); document.write( "Multiply equation by 4 to get rid of the denominator, results \n" ); document.write( "4x + (90-x) = 4(75) \n" ); document.write( "4x - x + 90 = 300 \n" ); document.write( "3x = 300 - 90 \n" ); document.write( "3x = 210 \n" ); document.write( "x = \n" ); document.write( "x = 70 degrees is the first angle \n" ); document.write( "then \n" ); document.write( "90 - 70 = 20 degrees is the second angle \n" ); document.write( ": \n" ); document.write( "Now, I will let you answer the following questions \n" ); document.write( ": \n" ); document.write( "What is the measure of the smaller angle? \n" ); document.write( "What is the measure of the other angle? \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Check solution in the statement \n" ); document.write( "\"The sum of the measure of the first angle and 1/4 of the second angle is 75 degrees.\" \n" ); document.write( ": \n" ); document.write( "You are right!
