Step-by-step explanation:
I’m pretty sure the answer is C.
You're looking for the number 13 and 7 can go into.
You can use the listing method.
13: 13, 26, 39... and so on, and so on.
7: 7, 14, 21, 28, 35, 42, 49.... and so on.
An easier way to do it is to simply multiply 13 by 7.

13 and 7 can go into 91, evenly.

ASA
Step-by-step explanation:
In ΔBAD , ΔBCE
∠BAD = ∠BCE
AD= EC { GIVEN}
∠ABD = ∠CBE { COMMON TO BOTH TRIANGLES}
Quick answer
Any irrational number. I can't think of any exception to this statement.
sqrt(5) is irrational. 1/2 * sqrt(5) is still irrational.
-sqrt(5) is irrational. -1/2 * sqrt(5) is still irrational
2 + sqrt(5) is irrational. Multiplying this by 1/2 is still irrational.
1/2(2 + sqrt(5) = 1 + 1/2 * sqrt(5) ) is irrational.
Conclusion
There are no exceptions to this. All irrational numbers produce irrationals when multiplied by 1/2
