1. diketahui :
b= 6 cm
LA=  75^{o}
LC =  60^{o}
LB =  180^{o} - ( 75^{o} + 60^{o} )
LB =  180^{o} -  135^{o} =  45^{o}

 \frac{b}{sin B} =  \frac{c}{sin C}
[tex\frac{6}{ \frac{ \sqrt{2} }{2} } = \frac{c}{ \frac{ \sqrt{3} }{2}} [/tex]
 [tex]\frac{6 \sqrt{3}}{ \sqrt{2} } .  \frac{ \sqrt{2} }{ \sqrt{2} } = c[/tex]
 \frac{6 \sqrt{6} }{2}  = c
c = 3 \sqrt{6}

2. panjang setiap sisi = 12 cm
panjang diagonal AC :
AC =  \sqrt{12 ^{2} + 12 ^{2}}
AC =  \sqrt{36.8}
AC =  6\sqrt{8}}

semoga membantu :)
