Line xy is perpendicular to line cd at d. which conclusion can be drawn?

I have attached the choices given for this question

measure angle XDC = 90 degrees

Explanation:
The term "perpendicular" implies that the angle formed between the two lines is 90 degrees.
These two lines do not have to be equal in length, they just intersect forming a 90-degree angle.

Comparing the explanation with the given choices, we would find that the only correct choice is:
measure angle XDC = 90 degrees

Hope this helps :)
