You can put this solution on YOUR website!
The sum of the angles of any triangle = $\"+180+\"$ degrees
\n" ); document.write( "One of the angles of a right triangle must be $\"+90+\"$ degrees
\n" ); document.write( "You are given that one angle is $\"+25+\"$ degrees
\n" ); document.write( "--------------------------------------------
\n" ); document.write( "Let $\"+alpha+\"$ = the 3rd angle
\n" ); document.write( " $\"+90+%2B+25+%2B+alpha+=+180+\"$
\n" ); document.write( " $\"+115+%2B+alpha+=+180+\"$
\n" ); document.write( " $\"+alpha+=+180+-+115+\"$
\n" ); document.write( " $\"+alpha+=+65+\"$ degrees
\n" ); document.write( " \n" ); document.write( "
