There is a scalene triangle, where point A is at the top and it says that A represents (30x)degrees, B says (40x)degrees, and C represents (10x)squared. My teacher said to use to use factoring or the quadratic formula. The lesson is \"The Triangle Sum Theroem\". Thank you so much for your time. I just cannot do these!!<BR>\n" );
