Question 1111683: 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 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.

Add the measures of the two angles you are given and subtract from to get the measure of the third angle. 113 + 47 = 160, 180 - 160 = 20

Use the Law of Sines:



Just plug in numbers:



The rest is calculator work. Calculate and from the relationship above, then calculate
