\(x=\sqrt{\dfrac{313}{24336}}\left(đvđd\right)\)
Áp dụng HTL ta có:
\(\dfrac{1}{AB^2}+\dfrac{1}{AC^2}=\dfrac{1}{AH^2}\)
\(\Rightarrow\dfrac{313}{24336}=\dfrac{1}{x^2}\)
\(\Rightarrow x^2=1:\dfrac{313}{24336}\)
\(\Rightarrow x^2=\dfrac{24336}{313}\)
\(\Rightarrow x=\sqrt{\dfrac{24336}{313}}\approx8,82\)
