Maintaining the same width of the compass as AB, draw an arc from point X such that it intersects the afternoon drawn from N in a point
Assuming 0x6A is given in base 16, first convert
and
to a common base, say base 10:


Then



You have 3 coins and you want 2 get heads, so you make the 2 and 3 a probability and you get 2/3
The distance from Ship B to the signal fire at point C is 
Explanation:
It is given that two ships A and B are at a distance 140 ft from each other.
The angle formed by ship A is 82º and the angle formed by ship B is 78º.
To determine the distance from ship B to the signal fire at point C, we need to know the another angle.
Hence, we have,

Now, we shall solve the problem using the law of sines,

Substituting the values, we have,


Simplifying, we get,


Thus, the distance from Ship B to the signal fire at point C is
