Find the value of x that makes m || n

(A) and (D)

Step-by-step explanation:

From the given figure, it can be seen that ∠x and 50° form adjacent angle pair, thus using the straight line property, we have

∠x+50°+90°=180°

∠x+140°=180°

∠x=40°

Now, if we put x=40° and add with angle having measure 50°, it forms complementary angles.

Thus, The relationship between x and 50° is that they are adjacent angles and complementary angles.
