Question

(?) what is the relationship between the 81 degree angle ? what is the measure of this angle ?

Answer 1

Here the angle opposite to the 81 degree will also be 81 degree ( vertically opposite angles)
Now the angle opposite to x degree will be 82 (alternate angles)
And lastly x degree is equals to 81 degree( vertically opposite angle)

Answer 2

A. They are corresponding and vertically opposite
