You can put this solution on YOUR website!
Complementary angles are angles whose values, when added together, equal 90º.
\n" ); document.write( "Let angle A equal \"x+30\" and angle B equal \"x\", as the instructions state that angle A is thirty more than angle B.
\n" ); document.write( "Now you create an equation using this.
\n" ); document.write( "(x)+(x+30)=90
\n" ); document.write( "Combine your like terms, so your variables(x).
\n" ); document.write( "2x+30=90
\n" ); document.write( "Subtract the 30 from both sides, since the 30 is positive, to cancel it out.
\n" ); document.write( "2x=60
\n" ); document.write( "Divide both sides by 2 since the x has a coefficient, or number in front of it. You want to get the variable totally alone on one side of the equation.
\n" ); document.write( "x=30
\n" ); document.write( "Now check the answer by putting it back into the equation.
\n" ); document.write( "(30)+(30+30)=90
\n" ); document.write( "30+60=90
\n" ); document.write( "90=90
\n" ); document.write( "There's your answer.
\n" ); document.write( "Hope this helps! \n" ); document.write( "
