c^2 = a^2 + b^2 - 2(ab)(cos C)
c^2 + 2(ab)(cos C) = a^2 + b^2
2(ab)(cos C) = a^2 + b^2 - c^2
cos C = (a^2 + b^2 - c^2) / 2ab - Answer choice E
Hope this helps! :)
Blue dresses / total dresses = 1/(3 + 2 + 1) = 1/6 <==
X + y = 4
Is how you would write it in standard form.
Answer:
(x−5)^2+(y+6)^2=9
Step-by-step explanation:
Answer:
y = x + 2
Step-by-step explanation:
y = mx +b
m = slope
m = 3/3, m = 1
b = y-intercept
b = 2
