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.

Answer: x = -2
<u>Step-by-step explanation:</u>
vertical line means it will be x = ___
Set the x-values equal to each other and solve for x.
3 - 2x = x + 9
<u> +2x</u> <u>+2x </u>
3 = 3x + 9
<u>-9 </u> <u> -9 </u>
-6 =3x
-2 = x
X< - 1/8 let me know if Uu need work
