What is the measure of the third angle? The other two are 54degrees 53'55'', and 105degrees 32'43''
\n" ); document.write( "--------------
\n" ); document.write( "If it's a triangle, the sum of the angles is 180 degs
\n" ); document.write( "Add the 2 angles.
\n" ); document.write( "105degrees 32' 43''
\n" ); document.write( "+54degrees 53' 55''
\n" ); document.write( "-------------------------
\n" ); document.write( "159 degs 85' 98\"
\n" ); document.write( "---
\n" ); document.write( "98\" = 1' 38\"
\n" ); document.write( "--> 159 degs 86' 38\"
\n" ); document.write( "86' = 1 deg 26'
\n" ); document.write( "--> 160 deg 26' 38\"
\n" ); document.write( "-----------------------
\n" ); document.write( "Subtract that from 180 degs
\n" ); document.write( "180 degs = 179 deg 60' = 179 deg 59' 60\"
\n" ); document.write( "--------------
\n" ); document.write( "+179 deg 59' 60\"
\n" ); document.write( "-160 deg 26' 38\"
\n" ); document.write( "-------------------
\n" ); document.write( "= 19 deg 33' 22\"
\n" ); document.write( " \n" ); document.write( "
\n" );
