Step-by-step explanation:

Step 1: Define

Identify and set up

x + 81 + 65° + 40° = 180°

Step 2: Solve for x

[Addition] Combine like terms:                                                                        x + 186° = 180°[Subtraction Property of Equality] Subtract 186° on both sides:                   x = -6°
