Well you can start by drawing a triangle with the information
the size of angle B can be found using the Law of Sine

the size of angle C can be found using angle sum of a triangle.
The length of side c can be found using the Law of Cosines

hope it helps
Answer: -9.5, -.82, 8/10, 2.5
Step-by-step explanation:
-9.5 is the least because the bigger the negative number is the smaller it's value is (opposite of positive numbers)
-.82 same thing
8/10 or .8
2.5 same thing as 2.50 so what is greater $2.50 or $0.80 exactly 2.50 is greater so it's the greatest
Total distance covered = 5 x 30 = 150 miles
Angle of travel with respect to south pole = 180 - 164°56' = 15°4'
Let the distance southwards covered be x, then
cos 15°4' = x/150
Thus, x = 150 cos 15°4' = 144.84
Therefore, the distance covered southwards = 145 miles to the nearest mile.
