You can put this solution on YOUR website!
First, find the angle. Let A be the Angle, and C be it's complement.
\n" ); document.write( "Since the angles are complimentary, you can write this equation:
\n" ); document.write( "Equation #1: \"A%2BC=90\"
\n" ); document.write( "From the information given, you can write this equation:
\n" ); document.write( "Equation #2:\"C=0.5A-15\"
\n" ); document.write( "You have 2 equations with two unknowns. Solve Equation #1 for C:
\n" ); document.write( "\"C=90-A\"
\n" ); document.write( "Substitute this expression for C into Equation #2:
\n" ); document.write( "\"90-A=0.5A-15\"
\n" ); document.write( "Solve for A:
\n" ); document.write( "\"-1.5A=-105\"
\n" ); document.write( "\"A=70\"
\n" ); document.write( "Now that you have the angle, you can find its supplement (S) via the following equation:
\n" ); document.write( "\"70%2BS=180\"
\n" ); document.write( "\"highlight%28S=110%29\"
\n" ); document.write( "=============
