鬥快找出 X 的值

我覺得係 13
因為係 畢氏定理的三角數。
3^2 + 4^2 = 5^2
6^2 + 8^2 = 10^2
5^2 + 12 ^ 2 = 13^2
所以 X = 13

既然有第二個答案,
咁應該係19..
因為頭兩行都係等差數列

13(畢氐定理),19(等差),3 or 7(x形睇)

I Think The Solution Of x Will Be 13,
Explain From Pythagora's Theorem,
a^2 + b^2 = c^2
In A Right Angle Triangle,
If TheOpposite-Side,Adjacent-Side And Hypotenuse
Is 3,4.5 Respectively,
Than It Can Use In a^2+b^2=c^2(Pythagoras' Theorem),
And 6,8,10 Can Create An RiAQght Angle Triangle In The Theorem As Well,
So I Think The Answer Is 13 Of x

答案有兩個.

3,4,5
6,8,10
呢2組數各組差ge數都係一樣
所以5,12,x
x=19
因為5同12差7,將7加番12就係19(

我估係9,15,100,應該係囉..................................我唸
