Solve word problems that involve general triangles using trigonometry.


Perched upon Pinnacle Point, Peter picks up a peculiar piece of parchment (pictured below).
"This might be a treasure map!" he exclaims as he flips it over, revealing a clue:
spaceP. Point. 673 paces
spaceS. Cove. 861 paces
spaceUnder big rock
“These must be the distances to the treasure!” Peter nearly wets himself.
If Peter is currently facing towards Skeleton Cove, how many degrees to his left should he turn before walking 673 paces to the treasure?
Do not round during your calculations. Round your final answer to the nearest degree.
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, p, i or 2, slash, 3, space, p, i
