Answer:
I think it is acute because if the angle was over 90 degrees it would be and obtuse then

Answer:
Step-by-step explanation:
In parallelogram adjacent angles are supplementary
∠U +∠V = 180
9x + 15 + 6x + 15 = 180
Combine like terms
9x + 6x + 15 + 15 = 180
           15x + 30 = 180
Subtract 30 from both sides
           15x = 180 - 30
          15x = 150
Divide both sides by 15
             x = 150/15
x = 10
∠U = 9x + 15 
       = 9*10 + 15
       = 90 + 15
∠U = 105
∠V = 6x + 15
      = 6*10 + 15
      = 60 + 15
∠V = 75
