Answer:

100°

Step-by-step explanation:

The bottom left and top left angle in a parallelogram are adjacent angles.

From the properties of parallelogram, we know adjacent angles are supplementary, this means they "add up to 180°"

Thus, if one angle is 80, the other angles would be 100 (to make it total 180).

So, top left corner angle measures 100°
