Take the square root. A 2 b 2 c 2 2 b c cos. Then the law of cosines states.
This resembles the pythagorean theorem except for the third term and if c is a right angle the third term equals 0 because the cosine of 90 is 0 and we get the pythagorean theorem.
C2 82 112 2 8 11 cos 37ยบ do some calculations. Then the law of cosines states. Write the law of cosines and replace the letters with the values. A 2 74 45 924.
