Answer:
Part a): 100 degrees
Part b): Isosceles Triangle
Step-by-step explanation:
Part a): Since the angle measures of all triangles add up to 180 degrees and since the other two angles are 40 degrees, which add up to 80, we can use subtraction to find the answer.
180 - 80 = 100
Part b): Since only two of the three angles in this triangle have the same measure, we can find that it is an isosceles triangle, with base angles measuring 40 degrees, and the vertex angle being 100 degrees.
 
        
             
        
        
        
Answer:
the width is 3.5 in.
Step-by-step explanation:
u get it by dividing 182 in and 52 in and u get 3.5 In
 
        
                    
             
        
        
        
I believe 10% because 390 and 39 are exactly the same numbers almost
