Final answer:

The degree measure of each angle of the parallelogram is approximately 89.1° and 126.8°.

Step-by-step explanation:

The sum of the angles of a parallelogram is always 360 degrees. In this case, the given angles are ((3x-4)°) and ((4x-1)°).

Since the opposite angles of a parallelogram are congruent, we can set up an equation:

  • ((3x-4)°) + ((4x-1)°) + ((3x-4)°) + ((4x-1)°) = 360°

Simplifying the equation, we get:

  • 6x - 10° + 6x - 10° = 360°
  • 12x - 20° = 360°
  • 12x = 380°
  • x = 31.7°

Now we can substitute the value of x back into the angles to find their measure:

  • ((3x-4)°) = ((3(31.7)-4)°) = 89.1°
  • ((4x-1)°) = ((4(31.7)-1)°) = 126.8°

Therefore, the degree measure of each angle of the parallelogram is approximately 89.1° and 126.8°.
