ekamiaww $\displaystyle\ \frac{AC}{\sin B}= \frac{BC}{\sin A} \\ \frac{\not{16}}{\sin 30^o} = \frac{\not{16} \sqrt{2} }{\sin A} \\ ~~~~~~~\frac{1}{ \frac{1}{2} } = \frac{ \sqrt{2} }{\sin A} \\ ~~\sin A= \frac{1}{2} \sqrt{2} \\ $maka, \\ A = 45^o \\ \tan A=\tan 45^o=1$

semoga membantu ya :)

alvinteguh Panjang AB = √16√2² - 16 = 16 cm
tan BAC = AC / AB = 16 / 16 = 1
