Answer:Hello! answer: 80Step-by-step explanation:When doing the Pythagorean theorem you do...a^2+b^2=c^2 which is just A multiplied byitself + B multiplied byitself that will equal the number that C multiplied by itself would equal then you just figure out what multiplied byitself equals that number and thats the answer so... 64 Γ 64 = 4096 48 Γ 48 = 23044096 + 2304 = 6400 80 Γ 80 = 6400 therefore c = 80 hope that helps!
