Answer 2

Step by step EXPLAINATION

Let a and b be the adjacet angles of a parallelogram.

Now, as we know that adjecent angles of a parallelogram are supplementary

Therefore, sum of angles a and b will be 180°.

= a+b= 180°

One angle is 2/3rd of the other -- a= 2/3b

➡️ 2/3b+b = 180°

➡️ 5/3b = 180°

➡️ b = 108°

➡️a = 2/3 × 108 = 72°
