A) \[6,6,6\]
B) \[6,\sqrt{34},6\]
C) \[7,\sqrt{34},7\]
D) None of these
Correct Answer: C
Solution :
[c] \[D\equiv \left( 3,2,0 \right)\] \[E\equiv \left( 3,0,3 \right)\] \[AD=\sqrt{{{(3)}^{2}}+{{(2)}^{2}}+{{(6)}^{2}}}=\sqrt{49}=7\] \[F=(0,2,3)BE=\sqrt{{{3}^{2}}+{{4}^{2}}+{{3}^{2}}}=\sqrt{34}\] \[CF=\sqrt{{{6}^{2}}+{{2}^{2}}+{{3}^{2}}}=7\] Thus. length medians be \[(7,\sqrt{34},7).\] Hence, option [c] is correctYou need to login to perform this action.
