Answer 1

Answer:

Step-by-step explanation:

∠A of parallelogram ABCD is 60°.

To find:-

∠D of parallelogram.

SolutiOn:-

We know that,

Sum of adjacent angles of parallelogram is 180°.

So,

∠A + ∠D = 180°

60° + ∠D = 180°

∠D = 180° - 60°

∠D = 120°

Therefore,

∠D of parallelogram ABCD is 120°.
