we can use the angle bisector theorem.
Bisector divide into equal parts.
Since ABCD is a parallelogram, we know that opposite sides are equal.
Using the angle bisector theorem, NO/MO = PN/MP. Substituting the given values, NO/20 = 12/8. Cross-multiplying, we find NO = 30 cm.
To calculate the measure of angle ABD in a trapezoid ABCD, where the diagonal BD bisects the angles at vertices B and D, we can use the property of a bisected angle.
