Answer:
Step-by-step explanation:
7). Since, ∠4 and ∠5 are the linear pair of angles,
     m∠4 + m∠5 = 180° [Supplementary angles]
     72° + m∠5 = 180°
     m∠5 = 180° - 72°
     m∠5 = 108°
8). Since, ∠6 and ∠7 are the vertically opposite angles,
     Therefore, ∠6 ≅ ∠7
     m∠6 = m∠7
     3x + 94 = 9x - 38
     9x - 3x = 94 + 38
     6x = 132
     x = 22
     m∠6 = 3(22) + 94 = 160°
     m∠7 = 9(22) - 38 = 160°
9). Since, ∠2 and ∠3 are the linear pair of angles, both the angles will be supplementary.
     m∠2 + m∠3 = 180°
     (13x + 54) + (2x + 36) = 180°
      15x + 90 = 180°
      15x = 90
      x = 6
      m∠2 = 13(6) + 54 = 132°
      m∠3 = 2(6) + 36 = 48°
 
        
             
        
        
        
Answer:
Clare is correct
Step-by-step explanation:
For two shapes to be congruent, the shape and size have to be the same. In other words they ate have to equal length in size and also equal angles(same shape hence equal angles). Therefore Clare is correct since only have equal length in sides does not qualify the polygon to be congruent or similar like Priya claims 
 
        
             
        
        
        
What kind of line? In order to answer this we have to know if its a graph line such as linear or if its a number line.
 
        
             
        
        
        
To find the slope ...
1) (5,-1)and(2,4)
4+1 / 2-5 
5/-3
So slope for #1 would be -3/5
