Hi, Hope I can help

\n" ); document.write( "two angles are supplementary. One has a measure of 58 degrees. Find the measure of the second angle.
\n" ); document.write( ".
\n" ); document.write( "Supplementary angles always add up to 180 degrees
\n" ); document.write( ".
\n" ); document.write( "If given one angle ( 58 degrees) we can find the other angle( we will say the unknown angle is \"x\" degrees)
\n" ); document.write( ".
\n" ); document.write( "Since they have to add up to 180 degrees, here is the equation
\n" ); document.write( ".
\n" ); document.write( "Unknown angle = \"x\" degrees
\n" ); document.write( "Known angle = 58 degrees
\n" ); document.write( ".
\n" ); document.write( "We add them together
\n" ); document.write( ".
\n" ); document.write( "\"+x+%2B+58+=+180+\" now all we do is solve for \"x\"
\n" ); document.write( ".
\n" ); document.write( "\"+x+%2B+58+=+180+\"
\n" ); document.write( ".
\n" ); document.write( "We will move 58 to the right side
\n" ); document.write( ".
\n" ); document.write( "\"+x+%2B+58+-+58+=+180+-+58+\"
\n" ); document.write( ".
\n" ); document.write( "\"+x+=+122+\"
\n" ); document.write( ".
\n" ); document.write( "We found \"x\", \"x\" = 122
\n" ); document.write( ".
\n" ); document.write( "The unknown angle is 122 degrees
\n" ); document.write( ".
\n" ); document.write( "We can check by replacing \"x\" with 122 in our equation
\n" ); document.write( ".
\n" ); document.write( "\"+x+%2B+58+=+180+\" = \"+122+%2B+58+=+180+\" = \"+180+=+180+\" (True)
\n" ); document.write( ".
\n" ); document.write( "The two supplementary angles are
\n" ); document.write( ".
\n" ); document.write( "First angle = 58 degrees
\n" ); document.write( "Second angle = 122 degrees
