Answer:
119°
Step-by-step explanation:
 
 
(Vertical angles) 
 
 
 
        
             
        
        
        
Congruent= the same shape and size.
area of the rectangle before it is divided=8*(area congruent rectangle)
area of the rectangle before it is dividide=8*(5 cm²)=40 cm²
Area of the rectangle before it is dividide=40 cm²
        
             
        
        
        
  -4x + 6y = -12
-4(0) + 6y = -12
     0 + 6y = 12
           <u>6y</u> = <u>12</u>  
            6      6
             y = 2
The y-intercept of the equation is 2.
        
             
        
        
        
Each Had 10. Y= 4. Because 3 x 4 = 12 + 8 = 20 ÷ 2 = 10
