Cho \( \Delta ABC \) có \(A \left( {2;3;1} \right), \, \,B \left( {2;1; - 2} \right); \, \,C \left( {3;3; - 1} \right) \). Tọa độ trực tâm \(H \) của \( \Delta ABC \) là:
A.\(H\left( { - \dfrac{{100}}{{29}};\dfrac{{99}}{{29}}; - \dfrac{{37}}{{29}}} \right)\)
B.\(H\left( {\dfrac{{100}}{{29}}; - \dfrac{{99}}{{29}}; - \dfrac{{37}}{{29}}} \right)\)
C.\(H\left( { - \dfrac{{100}}{{29}};\dfrac{{99}}{{29}}; - \dfrac{{37}}{{29}}} \right)\)
D.\(H\left( { - \dfrac{{100}}{{29}};\dfrac{{99}}{{29}};\dfrac{{37}}{{29}}} \right)\)
A.\(H\left( { - \dfrac{{100}}{{29}};\dfrac{{99}}{{29}}; - \dfrac{{37}}{{29}}} \right)\)
B.\(H\left( {\dfrac{{100}}{{29}}; - \dfrac{{99}}{{29}}; - \dfrac{{37}}{{29}}} \right)\)
C.\(H\left( { - \dfrac{{100}}{{29}};\dfrac{{99}}{{29}}; - \dfrac{{37}}{{29}}} \right)\)
D.\(H\left( { - \dfrac{{100}}{{29}};\dfrac{{99}}{{29}};\dfrac{{37}}{{29}}} \right)\)
