Your answer is A and D. adjacent angles and vertical angles.
<u>Adjacent angles and vertical angles.</u>
From the given figure, it can be seen that ∠x and 50° form adjacent angle pair. using the straight line property, we have
Now, if we put x=40° and add with angle having measure 50°, it forms complementary angles.
Thus, <u>option a and d </u> are the correct answers.
