Answer:
Smaller=18 degrees; larger= 162 degrees
Step-by-step explanation:
ok so first supplementary angles mean that the two angles added together will equal 180 degrees.
so 1x + 9x = 180 (combine like terms)
10x=180 (divide each side by 10)
x=18 
so the smaller angle is 18 because its only 1x, and the larger angle is 162 because 18x9=162
check: 18 + 162 = 180 
 
        
             
        
        
        
19 8/10 and if its simplified, 19 4/5
        
                    
             
        
        
        
Answer:
 B:25°
Step-by-step explanation:
Now  gets bisected by
 gets bisected by  .
.

Since, the angle is bisected, this means that the angle is split into two equal parts or the angle is halved.
We know that one of the angles is  so the other angle has to be
 so the other angle has to be  also.
 also.
Hence, the  .
