The ratio of the complements of two angles is 3:2 and the ratio of their
\n" ); document.write( "supplements is 9:8. Find the two original angles.
\n" ); document.write( "----------------
\n" ); document.write( "Let the two angles be x and y.
\n" ); document.write( "The complements are 90-x and 90-y
\n" ); document.write( "The supplements are 180-x and 180-y
\n" ); document.write( "------------------------
\n" ); document.write( "EQUATIONS:
\n" ); document.write( "1st: (90-x)/(90-y) = 3/2
\n" ); document.write( "2nd: (180-x)/(180-y) = 9/8
\n" ); document.write( "---------------------------
\n" ); document.write( "Simplifying 1st you get:
\n" ); document.write( "2(90-x) = 3(90-y)
\n" ); document.write( "180-2x = 270-3y
\n" ); document.write( "2x-3y = -90
\n" ); document.write( "---------------
\n" ); document.write( "Simplifying 2nd you get:
\n" ); document.write( "8(180-x)= 9(180-y)
\n" ); document.write( "8*180-8x = 9*180-9y
\n" ); document.write( "8x-9y = -180
\n" ); document.write( "----------------
\n" ); document.write( "Rewrite 1st and 2nd:
\n" ); document.write( "1st: 2x-3y = -90
\n" ); document.write( "2nd: 8x-9y = -180
\n" ); document.write( "--------------------
\n" ); document.write( "Multiply 1st by 4 and solve for y:
\n" ); document.write( "1st: 8x - 12y = -360
\n" ); document.write( "Subtract from 2nd to get:
\n" ); document.write( "3y = 180
\n" ); document.write( "y = 60
\n" ); document.write( "----------
\n" ); document.write( "Substitute into 2x-3y = -90 to solve for x:
\n" ); document.write( "2x-3*60= -90
\n" ); document.write( "2x = 90
\n" ); document.write( "x = 45
\n" ); document.write( "=============
