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

Step-by-step explanation:

This question can be illustrated using the attachment and the required bearing will be calculated using cosine theorem;

In this case:

Substitute these values in

Divide through by -112

Reorder

Take arccos of both sides

--- (approximated)

Hence, the bearing is approximately 38 degrees

answer: i literally just answered this question but they want me to do it again

step-by-step explanation:

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
