Answer:
6 feets
Step-by-step explanation:
The triangle described in the question has been sketched in the picture attached below :
From the triangle, we could solve for X, which is the base of the triangle using trigonometry :
Sinθ = opposite / hypotenus
Sin 30° = x / 12
0.5 = x / 12
x = 12 * 0.5
x = 6 feets
Hence base, x = 6 feets
Consider A to be at (0,0)
B lies on the circle with center at (0,0) and radius 190
The ship ended up at a point P on a circle with center at (0,0) and radius 270, such that BP = 180
If we let B be due north of A, then the bearing of P from B is z degrees, where
cosz = 80/180
Now you can find the angle θ that the ship is off via
tanθ = 180sinz/270 = 2/3 sinz
Vertex is (1,-4 )The parabola is going up
