k m n Note: Figure not drawn to scale. In the figure, line m is parallel to line n, and line k intersects both lines. Which of the following statements is true?
Correct answer: C (parsed from the explanation — this source omits an answer key for this item)
Explanation
Choice C is correct. Vertical angles, or angles that are opposite each other when two lines intersect, are congruent. It’s given that line k intersects line n. Based on 145° the figure, the angle with measure x° and the angle with measure are vertical 145 angles. Therefore, the value of x is equal to . Choice A is incorrect and may result from conceptual or calculation errors. Choice B is incorrect and may result from conceptual or calculation errors. Choice D is incorrect and may result from conceptual or calculation errors.
