Question

A=100 B=60 P=? un a parellogram ​

Answer 1

We know that opposites angles of a parallelogram are equal.

Therefore,

∠A=∠C=60 ∘

Also, we know that ∠A+∠B=180 ∘

60 ∘ +∠B=180 ∘

∠B=120 ∘

∠B=∠D=120 ∘

(opposite angles of parallelogram)

Answer 2

Answer:

We know that opposites angles of a parallelogram are equal.

Therefore,

∠A=∠C=60 ∘

Also, we know that ∠A+∠B=180 ∘

60 ∘ +∠B=180 ∘

∠B=120 ∘

∠B=∠D=120 ∘
