Final answer:
The solution to the geometry problem is Option 4: D = 120 degrees.
Step-by-step explanation:
The solution to the geometry problem is Option 4: D = 120 degrees.
To find the solution, we need to analyze the given options. Options 1, 2, and 3 provide angles for variables A, B, and C respectively, but none of them match the given options. Therefore, the correct answer is Option 4, which is D = 120 degrees.
