Answer:

Step-by-step explanation:

Let ABCD be a parallelogram in which ∠A=65∘

Since AD∥BC we can treat AB as a transversal. So,

∠A+∠B=180∘

65∘+∠B=180∘

∠B=180∘−65∘

∠B=115∘

Since the opposite angles of a parallelogram are equal, we have

∠C=∠A=65∘

 and ∠D=∠B=115∘

Hence, ∠B=115∘

,∠C=65∘

 and ∠D=115∘
