A ship sails 300km on a bearing of 078 how far north has the ship sailed

Answer 1

If this is a 78° bearing:

a/sinα=b/sinβ=c/sinγ

given:c=300; β=78°; sin90=1

α=12°

b/sin78=300

sin78*300=b

=293.44km

a=shortest side

b=mid length

c=hypotenuse

α angle opposite side a

β b

γ c

This is a rt triangle.
