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

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
