Answer:
63
Step-by-step explanation:
- We need to plug in b and c in order to solve for a. C is the long slanted side.
- [tex]12^{2}[/tex] - [tex]9^{2}[/tex] = [tex]a^{2}[/tex]
- 12 • 12 = 144, and 9 • 9 = 81.
- 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.
