Question

two adjacent angles of a parallelogram are (7x+25)° and (3x - 5)°. the value of x is ​

Answer 1

Answer:

16

Step-by-step explanation:

(7x+25) + (3x-5) =180

7x+3x+25-5 =180

10x + 20 = 180

10x= 180-20

10x = 160

x= 160/10

x= 16

Answer 2

Step-by-step explanation:

We know that,

Adjacent angles are equal to 180°

According to the question,

⟹ (7x+25)° + (3x - 5)° = 180°

⟹ 7x + 25 + 3x - 5 = 180°

⟹ 10x + 20 = 180°

⟹ 10x = 180 - 20

⟹ 10x = 160

⟹ x = 160/10

⟹ x = 16° ans.
