if j is 21 inches, k is 12 inches, and angle M measures 62 degrees, then find m using the Law is Cosines. round your answer to the nearest tenth

18.7

Step-by-step explanation:

The Law of Cosines is , where c is the unknown side length of a triangle, a and b are the remaining two side lengths, and C is the angle opposite to side c. To answer this question just plug in the known values:

Simplify:

m≈18.665...

When rounded to the nearest tenth, m=18.7

d≈7.07in
