Hello there, this is the answer for this problem, perhaps more algebraic than geometrical:\r
\n" ); document.write( "\n" ); document.write( "We have the largest angle designated as A, the second largest as B and the smallest as C.\r
\n" ); document.write( "\n" ); document.write( "Every step must be notated in order to get the equations.
\n" ); document.write( "We know that the largest angle is twice the second largest which means: A=2B\r
\n" ); document.write( "\n" ); document.write( "Also we know that one-third of the largest angle is 10 degrees larger than the difference of the other two, so, we have: (1/3)A=B-C+10\r
\n" ); document.write( "\n" ); document.write( "As our last equation, we know that the sum of all interior angles in a triangle is 180, that is: A+B+C=180\r
\n" ); document.write( "\n" ); document.write( "We have our three equations:\r
\n" ); document.write( "\n" ); document.write( " A=2B
\n" ); document.write( "(1/3)A=B-C+10
\n" ); document.write( " A+B+C=180\r
\n" ); document.write( "\n" ); document.write( "From there we solve them, results are:\r
\n" ); document.write( "\n" ); document.write( "A=102
\n" ); document.write( "B=51
\n" ); document.write( "C=27\r
\n" ); document.write( "\n" ); document.write( "Which, in this case, the one we need is the smallest angle, that is C, which is 27 degrees.
\n" ); document.write( "
\n" );
