Congruent because both angles are the same
Answer:
90 Degrees.
The angle which is equal to its supplement is 90 degrees.
If you set up a proportion, this will make sense.

Now, Cross Multiply
6x = 12.5
x = 25/12
12 + n
if you substitute n for any whole number and simplify. you will find that 12+n does not equal any others. for example, i used 6 in place of n and all equations gives you 10 except 12+n
hope this helps!
