Answer:
X = 11
Step-by-step explanation:
since the angles are supplementary that means their sum is 180
<em> </em>
</em>
 
        
             
        
        
        
(6x+9y=78) - (6x+4y=38) = (5y=40) = y=8
(2x+3(8)=26) = (2x+24=26) = (2x=2) = x=2
 
        
             
        
        
        
Answer:
I'm not sure what you want me to answer from this, so I solved for every variable:
Angle A: 83°
Side b: 6.29
Side c: 5.8
Step-by-step explanation:
-----Angle A:
Since the sum of the interior angles of a triangle ALWAYS equal 180°, we can solve for angle A as follows:

-----Side b:
Here, we use the sin rule for finding sides, since we know all of the angles as well as one side:

-----Side c:

 
        
                    
             
        
        
        
Answer:
(8,3)
Step-by-step explanation:
because its ON the line and the line is dotted. if the line was solid it would be a solution but it is not because the line is dotted
 
        
             
        
        
        
Answer:
x=30°
2x=60°
Step-by-step explanation:
Value of x°=x°/(2x°+x°)×90°
 = 1/3×90°
 =30°
Value of 2x°=30°×2
 =60°
