Adjacent angles are angles that share a common vertex and a common side. In a 80 degree angle, there are infinitely many pairs of adjacent angles that can be formed. Here are a few examples:
1. One pair of adjacent angles can be formed by drawing a straight line through the vertex of the 80 degree angle, creating two angles that add up to 180 degrees. One of the adjacent angles will be the 80 degree angle itself, and the other adjacent angle will be 180 degrees - 80 degrees = 100 degrees.
2. Another pair of adjacent angles can be formed by drawing a ray from one endpoint of the 80 degree angle that intersects the other side of the angle, creating two angles. One of the adjacent angles will be the 80 degree angle itself, and the other adjacent angle will be the difference between 80 degrees and the angle formed by the other side and the ray.
3. Yet another pair of adjacent angles can be formed by bisecting the 80 degree angle, creating two angles of 40 degrees each. These two angles will be adjacent to the original 80 degree angle.
Note that in all cases, the adjacent angles will share the same vertex and the same side as the original 80 degree angle.

Step-by-step explanation:
Draw a ray bisecting this angle.
...
Draw AOB = 80° using protractor.
With O as centre and a convenient radius, draw an arc cutting AO at N and OB at M.
With N as centre and a convenient radius, draw an arc.
Similarly, with M as centre and same radius, cut the previous drawn arc and name it as point C.
