Your question appears incomplete - there is no mention of angle B in the question. I have made a change to the question as i believe it should be - maybe you made an omission in copying or typing out the question.\r

\n" ); document.write( "\n" ); document.write( "The question as altered could be solved as follows.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "First let us note the applicable theorem in Geometry : The angles of a triangle add up to 180 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Assume angle B is x degrees. Since we are given that angle A is twice angle B, angle A could be denoted by 2x.Since We are given that angle C is 30 degrees more than angle A, we can denote angle C by 30+2x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence the total of all 3 angles of the triangle ABC could be denoted by
\n" ); document.write( "2x + x + 30+2x which should be equal to 180 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "i.e. 2x + x + 30+x= 180
\n" ); document.write( "i.e. 5x + 30 = 180
\n" ); document.write( "i.e. 5x = 150
\n" ); document.write( "i.e. x = 30\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence the angles of the triangle ABC are 60, 30 and 90 degrees respectively.
\n" ); document.write( " \n" ); document.write( "
\n" );
