Plis dong jawab 1-5 beserta cara. Soalnya bsk dikumpulin

1.
[tex] \frac{ < aob}{ < boc} = \frac{10}{bc} \\ \\ \frac{60}{150} = \frac{10}{bc} \\ \\ 60bc = 1500 \\ bc = 25 \: cm [/tex]
2.
[tex] \frac{ < foe}{ < goh} = \frac{91}{goh} \\ \\ \frac{70}{80} = \frac{91}{goh} \\ \\ 7goh = 728 \\ goh = 104 \:cm \\ \\ kalo \: soal \: ini \: aku \: kurang \: tau \: karena \: luas \: beda \: lgi [/tex]
