There is a trig application problem I have been working on over and over and arriving at the same answer, even when approaching the problem different ways. My answer is

126 but the answer in the back of my book is

130. Could you guys try to solve it?

Distance Across a Canyon

To find the distance across a canyon, a surveying team locates points A and B on one side of the canyon and point C on the other side of the canyon. The distance between point A and B is 85 yards. The measure of angle CAB is 68 degrees and the measure of angle CBA is 75 degrees. Find the distance across the canyon.

Thanks
