Answer:
m<B = 60°
m<C = 60°
m<F = 80°
m<G = 80°
Step-by-step explanation:
m<B = 180° - 120° = 60°
m<C = m<B = 60° (Vertically opposite angles are equal)
m<F = 180° - (40° + m<C(60°)) = 80°
m<G = 180° - (m<H + m<B) = 180° - (40° + 60°) = 80°

Answer:

Step-by-step explanation:
Area of any triangle could be always calculated as base length multiplied by the height perpendicular to the aforementioned base divided by 2. Therefore:
A = 18 * 11 / 2 = 198 / 2 = 99
 
        
             
        
        
        
Answer:
24 munchkins.
Step-by-step explanation:  
Let C be the number of chocolate and D be number of glazed donut holes in the original box.
We are told if Jacob ate 2 chocolate  munchkins, then 1/11 of the remaining Munchkins would be chocolate. We can represent this information as:

We are also told if he instead added 4  glazed Munchkins to the original box, 1/7 of the Munchkins would be chocolate. We can represent this information as: 
 
 
Upon substituting C's value from equation (2) in equation (1) we will get,
 
 
Let us have a common denominator on right side of equation.


Multiplying both sides of our equation by 7, we will get,

 
   
Multiplying both sides of our equation by 11, we will get,
 
  
 
 
 
 
 
  
 
 
 
  
 
 
 
 
Therefore, the total number of Munchkins in original box is 24.
