document.write( "We are given a triangle ABC. BC=1m,AC=6,6m and angle C=60degrees. \n" );
document.write( "We draw a segment BD From B cutting AC on point D.The angle CBD=90degrees. \n" );
document.write( "The triangle CBD is then rectangle on B. We are asked to find out the angle ABD. \n" );
document.write( "I hope I am being clear so far.\r \n" );
document.write( "\n" );
document.write( "So far, I've found out: \n" );
document.write( "CBD is a triangle rectangle with C=60degrees then angle D=30degrees. \n" );
document.write( "Also, BC=1m then CD=2m and BD=rt3m. \n" );
document.write( "The angle ADB= 180-30=150 degrees and AD=AC-CD=6,6-2= 4,6cm. \n" );
document.write( "So I know that the triangle ADB has angle =150degrees, BD=rt3m and AD=4,6m. \n" );
document.write( "That is where I stop. \n" );
document.write( "Thanks in advance for your help. \n" );
