Explanation
Choice D is correct. The sum of consecutive interior angles between two parallel lines and on the same side of the transversal is degrees. Since it's given that line is parallel to line , it follows that . Subtracting from both sides of this equation yields . Therefore, the value of is .
Choice A is incorrect. This is half of the given angle measure.
Choice B is incorrect. This is the value of the given angle measure.
Choice C is incorrect. This is twice the value of the given angle measure.
