Determine the measurements of all angles. Since the ratio of the angles is 4:5:9 and the total of all angles in a triangle add up to 180 degrees:\r
\n" ); document.write( "\n" ); document.write( "\"4x+%2B+5x+%2B+9x+=+180\"
\n" ); document.write( "\"18+x+=+180\"
\n" ); document.write( "\"x+=+10\" \r
\n" ); document.write( "\n" ); document.write( "\"4%2810%29+=+40+degrees\"
\n" ); document.write( "\"5%2810%29+=+50+degrees\"
\n" ); document.write( "\"9%2810%29+=+90+degrees\"\r
\n" ); document.write( "\n" ); document.write( "Draw a right triangle
\n" ); document.write( "Label the vertical side \"10\"
\n" ); document.write( "Label the angle opposite the vertical side \"40 degrees\"
\n" ); document.write( "(The smallest angle is always opposite the shortest side)
\n" ); document.write( "You will be solving for the hypotenuse (longest side); label the hypotenuse \"x\"\r
\n" ); document.write( "\n" ); document.write( "To solve for the hypotenuse use the sine function
\n" ); document.write( "Sine of an angle = opposite side/ hypotenuse
\n" ); document.write( "\"sin+40+=+10%2Fx\"
\n" ); document.write( "\"x+=+10%2Fsin+40\"
\n" ); document.write( "\"x+=+10%2F.6428\"
\n" ); document.write( "\"x+=+15.55\" degrees
\n" ); document.write( "
\n" );
