There are 3 islands A, B,C. Island B is east of island A, 8 miles away. Island C is northeast of A, 5 miles away and northwest of B, 7 miles away. What is the bearing needed to navigate from island B to C? Round to the nearest degree

The bearing needed to navigate from island B to island C is approximately 38.213º.

Step-by-step explanation:

The geometrical diagram representing the statement is introduced below as attachment, and from Trigonometry we determine that bearing needed to navigate from island B to C by the Cosine Law:

(1)

Where:

- The distance from A to C, measured in miles.

- The distance from A to B, measured in miles.

- The distance from B to C, measured in miles.

- Bearing from island B to island C, measured in sexagesimal degrees.

Then, we clear the bearing angle within the equation:

(2)

If we know that , , , then the bearing from island B to island C:

The bearing needed to navigate from island B to island C is approximately 38.213º.

the slope of the first function is -3. (3/1)

the slope of the second function is 1. (13-10/6-3).

since |-3| is greater than |1|, the function with the steepest slope is the first.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
