a=5 B=30
\n" ); document.write( "We know that if B=30 then the leg b=a/2 in a right triangle.(A=90 degrees).
\n" ); document.write( "So b=5/2=2.5 feet
\n" ); document.write( "c=sqrt(a^2-b^2) from the Pythagorean theorem.
\n" ); document.write( "c=sqrt[5^2-2.5^2)
\n" ); document.write( "c=sqrt(25-6.25)
\n" ); document.write( "c=sqrt18.75
\n" ); document.write( "c~4.33
\n" ); document.write( "c~4.33 feet\r
