Answer:
b should be correct
Step-by-step explanation:
no need to cash app me its been a while since ive done math so i dont even know if this is right
 
        
             
        
        
        
Yea what the other guy said
        
             
        
        
        
A.) A= (1/2)absinC
b.) sinA/a, sinB/b, sinC/c
 sin100/42, sin25/b, sinC/c
use these two fractions.
 sin100/42= sin25/b
cross multiply next
 b×sin100= 42×sin25
then divide on both sides by sin100
b=18
c.)measurementofA+measurementofB+measurementofC=180
100+25+C=180
125+C=180
-125 -125
The measurement of angle C is 55 degrees.
d.)A=(1/2)42×18×sin55
 = 21×18×sin55
 A =309.6 units squared
        
             
        
        
        
We know that there are (4^9)^5 ⋅ 4^0 at the library, so we just need to simplify this to get the answer.
(4^9)^5 ⋅ 4^0 
=(4^9)^5×1
=(4^9)^5
=4^9×5
=4^45. As a result, the total number of books at the library is 4^45 books at the library or B is the final answer. Hope it help!
