As given by the question
There are given that measure angle 1 is 160 degrees.
Now,
According to the properties, opposite angles are congruent.
Then,
We can say that the measure of angle 3 will also be 160 degrees.
And,
According to the properties:
The angles 2 and 3 will be equal to 180 degrees.
So,
Then,
Hence, the measure angles 2 and 3 are shown below:
