Answer :
Answer:
8.944 or 9
Step-by-step explanation:
Pythagorean Theorem states a^2 + b^2 = c^2. We have our c^2 and our a^2 so we just need to solve for a^2.
12 is the hypotenuse which means its c. 12^2 = 144.
8 is a leg which means its either a or b but we'll just call it a. 8^2 = 64
144 = 64 + b^2
144 - 64 = b^2
144 - 64 = 80
80 = b^2
[tex]\sqrt{80\\}[/tex] = b
[tex]\sqrt{80\\}[/tex] = 8.94427191 or 9
