Step-by-step explanation:
Because vertical angles are always equal, we want to solve 
.
We can add 10 to both sides to get 
.
We can subtract 
from both sides to get 
.
Lastly, we divide both sides by 20 to get 
.
So, 
and we're done!

Answer:
EBC and ABE, as well as ABD and ABE
Step-by-step explanation:
Supplementary angles form an 180 degree angle. In other words, they form a straight line.
EBA and DBC are each greater than 90 degrees and are vertical angles, not supplementary angles.
EBC and ABE form a straight line. So they are supplementary angles.
ABD and ABE form a straight line. So they are also supplementary angles.
CBE and ABD are each less than 90 degrees and are vertical angles, not supplementary angles.
So, EBC and ABE, as well as ABD and ABE are the correct choices.
