Answer:
The solution of the system is the ordered pair (-13,-4)
Step-by-step explanation:
we have
 -----> equation A
 -----> equation A
 ----> equation B
 ----> equation B
Solve the system by elimination
Multiply by 2 both sides equation B
 
 
 ----> equation C
 ----> equation C
Adds equation A and equation C

<em>Find the value of a</em>
substitute the value of b in any equation (i take equation B)



therefore
The solution of the system is the ordered pair (-13,-4)
 
        
                    
             
        
        
        
From right triangle trigonometry, we have the following:

, 
where the "opposite side" means the opposite side to angle with measure 

, and "adjacent side" means the adjacent side to angle with measure 

.

 is a constant which can be found using a calculator.
In the calculator of the pc press: view - scientific - 35 - tan.
 This gives 

Thus, back in the equation 

 we substitute as follows and solve:


Answer: 8.4 cm
 
        
        
        
Answer:
69 centimeters squared
Step-by-step explanation:
First, find the area of the big square = 11cm * 4cm = 44cm
Next, find the area of the leftover square = 5cm * 5cm =25cm
Add them together to get 69 centimeters squared
