Sin Ф=opposite/ hypotenuse
In this case:
sin 25º=9 in /c
c=9 in/ sin 25º
c≈21.3 in.
Answer: sin (25º), in this case can be used to find the lenght of the hypotenuse, and the length of this hypotenuse would be 21.3 in.
The eight is in the ten thousandths place
Answer:
It is proved that A is idempotent if and only if 
is idempotent.
Step-by-step explanation:
Case-1 : First assume that A is idempotent that is, 
. We have to show by using this 
. So,
Thus is idempotent.
Case-2 :
Conversly, assuming is idempotent, thet is, . We have to show . So,
Thus A is idempotent. Hence proved.
