Answer:

A. 45°

Step-by-step explanation:

When we are given two measurements of interior angles we add both of those angles together.

Also know that a triangle equals 180 degrees

So when we write out this expression     [tex]80+55+x=180[/tex]

[tex]135+x=180\\-135=-135\\x=45[/tex]

Hope this helps
