Answer 2

Step-by-step explanation:

In first figure, the arms are making 90 degrees. That is a fact.

Now, that means that 3 divisions = 90

So, 1 division = 30 degrees

So, in the second figure, the arms are making 30 degrees.

In the third figure, no. of divisions = 6

So, the angle made = 6 × 30 degrees = 180 degrees
