in a triangle ABC, angle b is 5 times angle A and angle C is 4 degrees less than 4 times angle A. what is the size of the angles?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We know by a theorem that the sum of the angles of a triangle equals 180. Let x be angle A. Then we have:\r
\n" ); document.write( "\n" ); document.write( "Angle A = x
\n" ); document.write( "Angle B = 5*x
\n" ); document.write( "Angle C = 4*x - 4\r
\n" ); document.write( "\n" ); document.write( "The sum of these must be 180 so:
\n" ); document.write( "x + 5*x + (4*x - 4) = 180\r
\n" ); document.write( "\n" ); document.write( "Solve the above for x then calculate 5*x and 4*x - 1. \r
