if m∠a=(3x)° and m∠d=(x+60)°, what value of x makes abcd a parallelogram?

  x = 30

Step-by-step explanation:

The figure will be a parallelogram when adjacent angles are supplementary:

  (3x)° + (x+60)° = 180°

  4x +60 = 180

  4x = 120

  x = 30

The value x = 30 makes the figure a parallelogram.

It also makes the figure a rectangle.
