Answer:
c
Step-by-step explanation:
that's all , all the best
90/3 parts of silver = 30 times multiplied by
tin = 12 × 30 = 360g
lead = 8 × 30 = 240g
12.5 / 23 = 0.5434 parts per metal
tin = 12 × 0.5434 = 6.5kg
lead = 8 × 0.5434 = 4.5kg
silver = 3 × 0.5434 = 1.5kg
It would be b because a^2+b^2=c^2 so in this case 5^2+8^2=c^2
