How do i do this, it is for geometry (ignore the answer it was a guess) you so much.

AC is about 41. 095 miles long.

Step-by-step explanation:

You can use the Law of Cosines to solve this: c^2 = a^2 + b^2 – 2ab cos(C)

Substitute in your values, and you're good to go!

c^2=16^2+28^2-2(16)(28)(cos(117))

c^2 = 256 + 784 - 896(cos(117))

c = sqrt(1040 - 896(cos(117)))

c is about 41. 095 miles long.
