I knew the answer sir 112 but hmmm I'm only 7 g
 
        
             
        
        
        
There is no ones place after the decimal so 3 is in the tenth place, so 2.4
        
             
        
        
        
2 because there are 4 numbers of edges and 4 vertices
        
             
        
        
        
Answer:
<em> 108 degrees</em>
Step-by-step explanation:
From the diagram we are given
Interior angles are 2x + 1 and 63 degrees
Exterior angle = 5x -2
The sum of interior angles is equal to the exterior angle
2x + 1 + 63 = 5x - 2
2x + 64 = 5x - 2
2x - 5x = -2-64
-3x = -66
x = -66/-3
x = 22 
Get the exterior angle:
Exterior angle = 5x-2
Exterior angle = 5(22) - 2
Exterior angle = 110-2
Exterior angle  = 108 degrees
<em>Hence the measure of the exterior angle is 108 degrees</em>
