If Peter is currently facing towards Skeleton Cove, how many degrees to his left should he turn before walking 673 paces to the treasure? Do not round during your calculations. Round your final answer to the nearest degree.

Angle = 59⁰

Step-by-step explanation:

First make  a sketch of the situation. This results in a triangle.

Now, since there are three sides, the law of cosines is applicable here. This is because we have three sides but unknown angles.

The law of cosines is as follows:

(BC)² = (AB)² + (AC) ² -2AB·AC·Cos A

Making Cos A the subject of the equation gives:

Cos (A) = [(AB)² + (AC)²- (BC)²]/[2AB·AC]

Cos A = [(673)² + (989)² - (861)²]/ (2×673×989)

Cos A = 689 729/ (1331194)

       A = Cos⁻¹ [689 729/ (1331194)]

          = 58.8⁰

          = 59⁰ (nearest degree)

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
