Answer:
Because the product is always non-termination,non-repeating decimal.
Step-by-step explanation:
If we have 
is irrational; 
is rational such that 
, then 
is irrational.
A way to represent this is:
Note that we have a contradiction, because is not a rational number, as I stated in the beginning. Therefore, ab is irrational.
Answer: -4
Step-by-step explanation:
Answer: I think it’s not similar becaus of the size.
It’s also a different number so it’s a no.
Step-by-step explanation:
Answer:
65 degrees
Step-by-step explanation:
The angles will sum up to 360, just do 360 - all known angles
360 - 90 - 128 - 77 = 65
The best way to do this is to make up values for the sides.
Say the lengths of square B's sides are each 4 cm. That means A's sides are 2 cm.
So, the area of square B is 4^2 = 16 cm^2, and A's area is 4 cm^2. We can see the shaded area is half of A, so it's 2 cm^2.
What percent of 16 is 2?
2 / 16 * 100 = 12.5%
