a triangle has three angles 110, 50 and 20. the longest side is 5 cm longer than the smallest side. Determine the perimeter of the triangle
\n" ); document.write( "------------
\n" ); document.write( "The smallest side is opposite the smallest angle.
\n" ); document.write( "x = length of smallest side
\n" ); document.write( "---
\n" ); document.write( "x/sin(20) = (x+5)/sin(110)
\n" ); document.write( "x*sin(110) = (x+5)*sin(20) = x*sin(20) + 5sin(20)
\n" ); document.write( "x*(sin(110) - sin(20)) = 5sin(20)
\n" ); document.write( "x = 5sin(20)/(sin(110) - sin(20))
\n" ); document.write( "x =~ 2.861267
\n" ); document.write( "Longest side = 7.861267
\n" ); document.write( "----
\n" ); document.write( "Find the 3rd side. Call it s:
\n" ); document.write( "x/sin(20) = s/sin(50)
\n" ); document.write( "s = x*sin(50)/sin(20)
\n" ); document.write( "s =~ 6.40856
\n" ); document.write( "================
\n" ); document.write( "Add those to find the perimeter.
\n" ); document.write( "
\n" );
