\n" );
document.write( "a. a=117 ft, b=16.35 ft  Applying the Pythagorean Theorem  a^2 + b^2 = c^2
\n" );
document.write( "  117^2 + 16.35^2 = c^2
\n" );
document.write( " c = 
\n" );
document.write( "b. ∠B = 8° 29' OR (57°24' = (8° + 29/60)° = 8.4833° and a =  32.8 ft 
\n" );
document.write( "  cos(8.4833°) = adj/hyp = 32.8 /c
\n" );
document.write( "    c = 32.8/cos(8.4833°) = 33.16
\n" );
document.write( "May find a if You wish by Applying the Pythagorean Theorem
