You can put this solution on YOUR website!
let y be the angle.
\n" ); document.write( "you get:
\n" ); document.write( "90 - y = x
\n" ); document.write( "180 - y = 4x
\n" ); document.write( "since x = 90 - y, you can substitute in the second equation to et:
\n" ); document.write( "180 - y = 4(90 - y)
\n" ); document.write( "simplify to get:
\n" ); document.write( "180 - y = 360 - 4y
\n" ); document.write( "subtract 180 from both sides of this equation and add 4y to both sides of this equation to get:
\n" ); document.write( "4y - y = 360 - 180
\n" ); document.write( "simplify to get;
\n" ); document.write( "3y = 180
\n" ); document.write( "divide both sides of this equation to get:
\n" ); document.write( "y = 60
\n" ); document.write( "that's your answer.
\n" ); document.write( "90 - y = = 90 - 60 = 30
\n" ); document.write( "180 - y = 180 - 60 = 120
\n" ); document.write( "120 is equal to 4 * 30.
\n" ); document.write( "this confirms the answer is good.\r
