Answer:

63

Explanation:

  1. We need to plug in b and c in order to solve for a. C is the long slanted side.

  2. 12^(2) -
    9^(2) =
    a^(2)
  3. 12 • 12 = 144, and 9 • 9 = 81.
  4. 144 - 81 = 63.

If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.
