How long is side "c" ... ?

We know angle C = 37º, and sides a = 8 and b = 11

have you taken trigonometry yet?

This might be quite impossible if you havent learned it yet.

Use the Law of Cosines

c^2 = 11^2 + 8^2 - 2(11)(8)cos (37°)

c^2 = 121 + 64 - 176cos(37°)

c^2 ≈ 44.44

The square root of 44.44 will give you your answer, CD

CuteDramione you probably havent learned the laws yet.

law of cosines:

c^2 = a^2 + b^2 - (2ab)C

where a b c are sides and C is angle
