Anggap: O di tengah BC maka TA = 3, AO = √6/2
TO² = TA² + AO² = 9 + 6/4 = 9 + 3/2 = 21/2 = 42/4
TO = √42 / 2
sin alfa = TA / TO = 3 / √42 / 2 = 6 / √42 = √42 / 7
maaf dri mna ya AO bsa dpt √6/2
BC = √6
AB.AC = AO.BC
√3.√3 = AO.√6
3 = AO.√6
AO = 3 / √6 = √6/2
untuk jwbn akhir kn 6/√42 knp bsa jd √42/7 itu bgaimna
oh iy sdah tau...trmksh ya!!!
6/√42 . √42/√42 = 6√42 / 42 = √42 / 7
