Find the value of x for which abcd must be a parallelogram

x = 7

Explanation:

Beacause lines AD and BC are parallel, the interior opposite angles formed by line BD are congruent or equal. Therefore, (3x-17) = (25-3x) Now solve for X:

First Add 3x to both sides: 6x-17=25

Add 17 to both sides: 6x=42

Last divide both sides by 6: x=7
