Answer:
75
Step-by-step explanation:
The measure of two supplementary angles =  15:21
The angles are  15x , 21x
15x + 21x = 180       {Supplementary}
          36x = 180
              x = 180/36
              x = 5
Smallest angle = 15 * 5 = 75
 
        
             
        
        
        
If this is an exponent, it would be 4 x 4 x 4 x 4 x 4 in expanded form.

b=(0,5)
Step-by-step explanation:
 
        
             
        
        
        
Here is the set using D = rt.
Jet 1: 
rate = 377 mph
time = x
Distance = 9128 miles
Jet 2:
rate = 275 mph
time = x
Distance = 9128 miles
Equation:
377x + 275x = 9128
You finish.
