A line is drawn from mid point of
\n" ); document.write( "the base up to the apex of the triangle.
\n" ); document.write( " This gives two right angled triangles
\n" ); document.write( "Base = 37/2 = 18.5cm
\n" ); document.write( "Base angle = 49 degrees (Given)
\n" ); document.write( "To find the length of the hypotenuse:-
\n" ); document.write( "Cos = Adjacent/Hypotenuse
\n" ); document.write( "Cos (49) = 18.5/Hypotenuse
\n" ); document.write( "Hypotenuse = 18.5/cos(49)
\n" ); document.write( "Hypotenuse = 28.2cm
\n" ); document.write( "This is the size of the two congruent sides.
\n" ); document.write( "Hope this helps.
