Which of the following equations correctly represents the law of cosines? A. 2 = 22 + b2 - 2ab. cos(B)
B. 2 = 22 + c2 - 2ac. cos(C)
C. a2 = b2 + c2 - 2bc. cos(A)
D. b2 = 22 +62 - 2bc. cos(B)

D. b2 = 22 + 62-2bc.cos(B)

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
