✔ 最佳答案
底部既對角線(diagonal)=√(8^2+8^2)=√128
由頂點垂直落泥會將對角線除2
=√128 / 2
=2(√ 8)
(12)^2 + (2(√ 8))^2 = x^2
144+32=x^2
x=13.27/13.3
ps. √=開方
如果你真係要用筆寫返既..我建議你自己設ABCD...係啲點到...會方便好多

Is it regular?
Consider the base
Hyp= (8^2+8^2)^0.5
=8(2)^0.5
Consider the right side perpendicular to the base with x
x=[(Hyp/2)^2+12^2]^0.5
x=13.266....
x=13.3(3sig fig)

Hyp is Hypotenuse

I have steps and if you do not understand, please write there.
