Question

 If ∠A and ∠B are two adjacent angles of a parallelogram. If ∠A = 70°, then ∠B = ? *​

Answer 1

Answer:

∠B = 110°

Step-by-step explanation:

As we know that any two adjacent angles of a parallelogram add up to 180°

∠A = 70° (Given)

∴ ∠A + ∠B = 180°

⇒ 70° + ∠B = 180°

⇒ ∠B = 180° - 70°

⇒ ∠B = 110°
