Answer:

180-45=135

Step-by-step explanation:

The unknown angle can be found by subtracting 180-45=135. ABC measures 180 because it is a straight angel and ABC meausres 45.

since ABC is a straight angle, it measures 180°. since you have 45° already, you can input it into an equation.

45 + x = 180

or

180 - 45 = x
