Answer:
ur correct it's A. trust me u look up all the definitions to the other than A. they gonna be wrong already looked em all up
3/5 cause you get the lowest common denominator
Use this version of the Law of Cosines to find side b:
b^2 = a^2 + c^2 − 2ac cos(B)
We want side b.
b^2 = (41)^2 + (20)^2 - 2(41)(20)cos(36°)
After finding b, you can use the Law of Sines to find angles A and C or use other forms of the Law of Cosines to find angles A and C.
Try it....
The answer is A.
From looking at the A graph, you must plug in the x variable into<span> y = -2x + 4.
y = -2(0) + 4 = 4
y = -2(1) + 4 = 2
y = -2(2) + 4 = 0</span>
