#3 </span><span>D Ira built his model using cross sections that were cut parallel to the base what shape was each cross section
</span>
The word "similar" from a math standpoint means to express proportionality. So long as two shapes have proportional sides, the exact lengths do not have to be equal. However, the angles need to be the same.
Answer:
the onw haldf
Step-by-step explanation:
No it does not make either too
Answer: x=2
57+x=25x
subtract x from both sides
57+x-x=25x-x
57=24x
divide by 24 on both sides
57÷24=24x÷24
x=2.375
I hope this is good enough:
