Answer:
We cannot solve without a value for x. The simplified form is 
Step-by-step explanation:
If the equation is  then we cannot solve it until we know the value of x. We can simplify it using order of operations such as PEMDAS.

Answer:
65
Step-by-step explanation:
Total degrees in triangle: 180
Angle 1= 50
We know that the other two angles are equal, so set it as "2x"
50 +2x= 180
2x=180
x=65
 
        
                    
             
        
        
        
Counter example, Two Points, point A& B can be in the plane while point C is out side if the plane.
