Rhombuses have acute and obtuse angles, so if it gives one just subtract it from 180
        
             
        
        
        
The only equation that works with x=-6 is A
 
        
             
        
        
        
The equation (form) is: 
The solution of the equation is: 
Explanation:
First, let's call the number we are going to solve for "x".
Then two thirds of this number can be written as:

Then "plus 4" means add 4 we get:

"is 7" means that the above expression is equal to 7 (as follows):

The solution of the above equation is:

 
        
             
        
        
        
Answer:
x = 76
Step-by-step explanation:
The inscribed angle x is half the measure of its intercepted arc.
x =  × (102 + 50) = 0.5 × 152 = 76
 × (102 + 50) = 0.5 × 152 = 76
