2. Sandra is participating in a cycle-a-thon to raise money for cancer research. 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 and 47, 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.
