Question

The adjacent angles of a parallelogram measure (3x + 8) and (10– x) degree. find the value of x​

Answer 1

Answer:

(3x+8) + (10-x) = 180°

3x + 8 + 10 - x = 180°

3x - x +8 + 10 = 180°

2x + 18 = 180°

2x = 180 - 18

2x = 162°

x = 162/2

x = 81°

Answer 2

we know that sum of adjacent angles of a parallelogram is 180°

(3x + 8) + (10 - X ) = 180°

3x + 8 + 10 - X = 180°

2x + 18 = 180°

2x = 180° - 18°

x = 162°/2

x = 81°
