one angle is 90.
\n" ); document.write( "the smallest angle will be acrtan(1/4) = 14.03
\n" ); document.write( "The last angle = 180-90-14.03 = 75.97
\n" ); document.write( "A
\n" ); document.write( "| 1
\n" ); document.write( "--------4----B find the inverse Tangent (tan^-1 or arctan) of the angle formed at vertex B.
\n" ); document.write( "
\n" );
