Answer:
0.
Step-by-step explanation:
The angle whose sine is 5/12 = 22.62 degrees and in Quadrant II it is 
180 - 22.62 degrees
The angle whose tan is (5/12)  = 22.62.
So we can write  α as 180 - α  and β as α.
sin (α+β) = sin ( 180 - α = α) = sin 180
= 0.

Answer:
5/4
Step-by-step explanation:
5*3/12=5*1/4=5/4
 
        
             
        
        
        
23/103 = 0.22 
0.22*100 = 22% 
The percentage increase is 22%
Hope that helps!
