So the way to figure out the sides of a right triangle, is basically
A^2 + B^2 = C^2
Letter A is the only one that would work, because the first number squared (times itself), added to the second number squared, would equal the third number squared. This is a basic principle of the pythagorean theorem, which I can explain in more detail if you'd like. :)
The answer to 9≤c+1 is c ≥ 8
Answer:

Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal
so
In this problem
If polygon RSUPE is similar to polygon KQUIC
then

substitutes the values and solve for a
