The course that has been set up for participants to travel is in the shape of a triangle. Two of the angles of the course are 113 degrees and 47 degrees , and the length of the side between these two angles is 4.1 km. For each kilometre that Sandra cycles, she will raise $14.70 for cancer research. Determine how much money Sandra raises if she cycles the course 3 times.\r<BR>\n" );
