1 1/2 as a improper fraction is 3/2
2 as a fraction is 2/1.
Multiply: 3/2×2/1=6/2.
Simpliy: 6/2=3.
Therefore, the answer is 3.
We use the law of Cosines to find b=AC opposite B
We know all the sides of triangle ABM so we can use the law of Cosines, this time to solve for
Substituting,
Answer: AC=√39
