Answer:
D.
Step-by-step explanation:
It's impossible to know if either A or B is true based on the information given to us in the diagram, so it cannot be A or B. C is false because all three of the angles in a triangle add up to 180°, and the equation in C only includes two angles. So the answer is D because it is the only statement we know to absolutely be true. Both angles three and four share one line (a line is 180°), so their sum must be 180°.
