Starting at point A, a ship sails 57 km on a bearing of 188°, then turns and sails 37 km on a

bearing of 330°. Find the distance of the ship from point A.

2 answers

the best way I could think of is break the distances into horizontal (x) and vertical (x) components and use Pythagorean theorem to find the distance of the ship from point A.

x= 57cos188 + 37cos330
y= 57sin188 + 37sin330

x^2 + y^2 = c^2
find c.
