Question

one angle of a parallelogram is 30 degree more than its adjacent angle how much does each measure​

Answer 1

Answer:

x+x+30=180

2x=180-30

2x=150

x=75

Answer 2

Let its adjacent angle be x.

so ,

Sum of adjacent angles or a parallelogram is 180° { because they are co-interior angles }

so,

x + x + 30° = 180°

2x = 180° - 30°

2x = 150°

x = 150/2

x = 75°

One angle measures 75° while the other 105°
