Hope that helps.Have a nice day!! ^^

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....

Since the shape is a quadrilateral, the interior angles add to 360 degrees. Thus, angle C is 360 - 82 - 92 - 102 = 84 degrees.
