Answer 1

Answer: 45.13 m

Step-by-step explanation:

Consider 2 triangles ABC with angle 30 and DBC with 40, where BC = 80 m (perpendicular)

Considering ABC,

tan 30 = BC/AB

tan 30 = 80/AB

0.57 = 80/AB

AB = 80/0.57

AB = 140.35

And in triangle DBC,

tan 40 = 80/DB

0.84 = 80/DB

DB = 80/0.84

DB = 95.23

Distance between ships = AB-DB

= 140.35-95.23

= 45.12 m
