ZA = 78º and ZC = 120°, find angles B and D.
A
2. In a trapezium ABCD, side AB is parallel to side DC. If ZA = X and ZD = (3x - 20)";
find the value of x.​

Answer 1

I hope this helps
I used this property of trapeziums :
Adjacent angles on the non parallel sides are supplementary which means that the sum of the 2 angles adjacent to each other on the non parallel sides AD and BC is 180 degrees
