Để giải bài toán này, ta có thể áp dụng định lý Pythagoras trong tam giác vuông. Gọi hai cạnh góc vuông của tam giác vuông là 5x và 6x (với x là một số thực dương), ta có:

(5x)^2 + (6x)^2 = (122)^2
25x^2 + 36x^2 = 14884
61x^2 = 14884
x^2 = 14884/61
x^2 ≈ ***
x ≈ √***
x ≈ 15.60

Vậy độ dài hai cạnh góc vuông lên cạnh huyền của tam giác vuông là 5x ≈ 5 * 15.60 ≈ 78 cm và 6x ≈ 6 * 15.60 ≈ 93.60 cm.
