Answer:
Each angle is 67 degrees
Step-by-step explanation:
Bisected angles are divided in half
134/2 =67
Each angle is 67 degrees
 
        
             
        
        
        
Answer:

Step-by-step explanation:
we know that
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
see the attached figure to better understand the problem
so
∠DEF=∠ECD+∠CDE
substitute the given values

solve for x
Combine like terms

Group terms



Find the measure of angle CDE

substitute the value of x

 
        
             
        
        
        
Answer:
So basically the answer is where the lines intersect if they do not intersect there is no solution if they are on top of one another it is infinite solutions
Step-by-step explanation:
 
        
             
        
        
        
16 units. Start from -2 and count up to 14. Basically -2+2+2+2+2+2+2+2+2+2 since the scale is by 2
 
        
             
        
        
        
Answer:
-1078
Step-by-step explanation:
To find the nth term in an arithmetic sequence we use the following formula
aₙ=a₁+(n-1)*d
Where a₁ is the first time, and d is the common difference (in this case -20) 
So we have
2+(55-1)*-20
2+(54)*-20
2-1080
-1078
