jika jawaban yg benar 7/3 √6 bagaimana caranya? god bless u kak

[tex] \frac{ac}{ab} = \tan( \alpha ) \\ \frac{7 \sqrt{3} }{x} = \tan(60) \\ \frac{7 \sqrt{3} }{x} = \frac{ \sqrt{3} }{1} \\ 7 \sqrt{3} \times 1 = x \times \sqrt{3} \\ 7 \sqrt{3} = x \sqrt{3} \\ x = 7 \sqrt{3 } \div \sqrt{ 3} \\ x = 7[/tex]
