Answer:
3.6° = ext. angle
Step-by-step explanation:
For the shape to be a regular polygon, all interior angles must be congruent.
We can find every interior angle by using the formula:




176.4 = each int. angle
We also know that int. and ext. angles are supplementary!
180 = 176.4 - x
3.6° = ext. angle
 
        
             
        
        
        
Answer:
11.4 units
Step-by-step explanation:
a/sinA = b/sinB 
17/sin(88) = b/sin(42)
b = sin(42) × 17/sin(88)
b = 11.3821540088
