Answer:
D 90
Step-by-step explanation:
x/4 ≥ 20
Multiply each side by 4
4*x/4 ≥ 20*4
x ≥ 80
The only number greater than or equal to 80 is 90
For any equation,
assume solution of a form, 
Which leads to,
Simplify to,
Then find solutions,
For non repeated real root y, we have a form of,
Following up,
For two non repeated complex roots 
where,
and,
the general solution has a form of,
Or in this case,
Now we just refine and get,
Hope this helps.

Answer:
120
Step-by-step explanation:
based on the plot the closest number to the patter seem to be around 100 but its not 90 as 90 would be below so it has to be about 12
We know that 1 side is 100 and 1 angle is 90 degrees
we would need at least 1 more angle or 1 more side length to say that they are similar
no
but, if we asssume that DCB is a straignt line, then we can say that they are similar
2. if we say taht they are similar then DE=AB, so then 175=DE=AB
