A surveyor stands at a point on the bank of a lake. She finds that her distance to a point on the right side of the lake is 65 yards and her distance to a point on the left side of the lake is 105 yards. The angle formed between these 2 sightlines is 80 degrees. How far apart are the 2 points on the sides of the lake? (This is a calculus triangle questions using sines/cosines) THANKS!!!!
