Question

two adjacent angle of a parallelogram are 3 x minus 4 and 3 X + 16 find the value of x and hence find the measure of each of its angle answers detail in brainly .com

Answer 1

Adjacent angles of a Parallelogram = 180°

Given,

3x + 16 + 3x - 4 = 180
6x +12 = 180
x = 168\6
x = 28

Now, 1st angle = 3x - 4 = 3*28 - 4 = 80°
2nd angle = 3x + 16 = 3*28 + 16 = 100°
