Using property
Sum of adjacent angles = 180
3x -4 + 3x + 16 = 180
6x + 12 = 180
6x = 168
x = 28
So each angle is
3x - 4 = 3x28 - 4 -= 80
3x + 16 = 3x28+16=100
Sum of adjacent angles = 180
3x -4 + 3x + 16 = 180
6x + 12 = 180
6x = 168
x = 28
So each angle is
3x - 4 = 3x28 - 4 -= 80
3x + 16 = 3x28+16=100

Step-by-step explanation:
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. The two adjacent angles of a parallelogram = 180 degrees. (3x + 16) = 100 degrees.
