Answer:
x = 69
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles in a triangle
x+90 = 159
Subtract 90 from each side
x +90-90 = 159-90
x =69
 
        
                    
             
        
        
        
Setup: 4x-6=3x+4 
<span>4x=3x+10 </span>
<span>1x=10 </span>
x = 10
