Answer:
No, they aren't similar.
Step-by-step explanation:
<u><em>Let's take the proportionality of their sides to check whether they are similar or not:</em></u>

=> 2 ≠ 3
So, they are not similar.
Answer:
The square root of 31 is 5.5 (not including numbers after that, just those two work) therefore it's in between the two numbers of 5 and 6.
Let's call the weight of an ostrich o=180.
we know that o=20+4*k, or, if we substitute o for 180: 180=20+4*k
where k is the weight of a kiwi.
if we want to know k, we have to subtract 20 from both sides of the equation first:
160=4*k
and divide them by 4:
40=k
So a kiwi is 40 inches high.
