Answer:
? = 7/2 
Step-by-step explanation:
? = x 
a denominator can’t be equal to 0 
x ≠ 0 
14/x = 4 
14 = 4x 
x = 7/2 
 
        
             
        
        
        
The answer would be 10 because if u put abcde over fghij, hi and cd are the same place so its the same answer or a mulitple of 10
        
             
        
        
        
Answer:
   ∠a = 39°
   ∠b = 129°
Step-by-step explanation:
Vertical angles are congruent. An exterior angle of a triangle is equal to the sum of the remote interior angles.
<h3>Application</h3>
Angle y and angle 'a' are vertical angles, so congruent.
   ∠a = ∠y = 39°
The angle marked 'b' is an exterior angle to the triangle. Its remote interior angles are 'a' and the one marked 90°.
   ∠b = ∠a +90° = 39° +90°
   ∠b = 129°
