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
