Answer:
45°
Step-by-step explanation:
A parallelogram is a polygon with 4 sides and 4 angles (that is a quadrilateral). 
For a parallelogram ABCD, Opposite sides and opposite angles are equal (i.e. BC = AD and ∠A = ∠C).
Consecutive angles are supplementary that is ∠A + ∠B = 180°.
The diagonals of a parallelogram bisect each other also separating the parallelogram into two congruent triangles.
In parallelogram HIJK, ∠H and ∠J are opposite angles. hence:
∠H = ∠J (opposite angles of a parallelogram are equal)
∠J = 45°
 
        
             
        
        
        
Answer:
the nominator could be any number here 
 
        
                    
             
        
        
        
12x = 10x + 3 
Subtract 10x from both sides
2x = 3 
 Divide by two on each side
x = 3/2 or 1 1/2 hours
Distance of the trip:
12 * 2 * 3/2 = 36 miles
How long does the trip take:
3/2 + 3/2 + 3/10 = 3 3/10 hours
        
                    
             
        
        
        
Answer:
EF = ~3.8
Step-by-step explanation:
Apply the sine theorem:
EF/sinD = DE/sinF
=> EF = DE*(sinD/sinF)
          = 3*(sin75/sin50)
          =3.78 = ~3.8
Hope this helps!
