The sum of the tree angles is 180 degrees, so:
\n" ); document.write( "First+Second +Third=180 degrees Subtract First from each side.
\n" ); document.write( "Second+Third=180 degrees-First Subtract Second from each side
\n" ); document.write( "Third=180 degrees-First-Second Plug in values
\n" ); document.write( "Third=180 degrees-58 degrees-52 degrees
\n" ); document.write( "Third=70 degrees ANSWER: The third angle measures 70 degrees. \r
