It’s B because 21% of 157 is 32.97 which then you would then add with the 157 people already there and get 189.97 and since you cannot have .97 of a person you round it up to 190
        
             
        
        
        
What is the question if it 98-49 than it would be 49

Answer:
Approximately mMK is 53 degrees 
Step-by-step explanation:
Here, we want to find the length of MK
As we can see, we have a right triangle at LNK
so
let us find the angle at L first 
9 is adjacent to the angle at L and also, 15 is the hypotenuse of the angle at L
so the trigonometric identity that connects adjacent to the hypotenuse is the cosine
It is the ratio of the adjacent to the hypotenuse 
So;
cos L = 9/15
L = arc cos (9/15)
L = 53.13 degree 
Approximately, L = 53 degrees 
so now, we want to get the arc length MK
We are to use the angle-arc relationship here 
Using this; arc length MK is equal to the measure of L at the center which is 53 degrees
