Answer:

≈ 3.9 miles

Explanation:

The third angle in the triangle is

180° - (53 + 78)° = 180° - 131° = 49°

Using the Sine rule in the triangle with distance from 2 being x, then


(3)/(sin49) =
(x)/(sin78) ( cross- multiply )

x × sin49° = 3 × sin78° ( divide both sides by sin49° )

x =
(3sin78)/(sin49) ≈ 3.9 ( to the nearest tenth )
