Question 754853: TWO ADJACENT ANGLES OF A PARALLELOGRAM ARE (3X-4) AND (3X+16) FIND THE VALUE OF X AND HENCE FIND THE MEASURE OF EACH OF ITS ANGLES

You can put this solution on YOUR website!
The two adjacent angles of a parallelogram = 180 degrees.
Therefore (3x - 4) + ( 3x + 16) = 180
6x + 12 = 180
6x = 180 - 12
6x = 168
x = 168/6
x = 28 degrees
Therefore (3x - 4) = 80 degrees
(3x + 16) = 100 degrees.
Hope this helps
