In the figure above, which of the following is true?

(A) y + z = x

(B) y = 90°

(C) x + y + z= 180°

(D) y = x + z

(E) z = x + y

\(x + 90 - y + 90 - z = 180\)
\(x = y + z\)

A. is correct

Look closely and you can make another line parallel to the other 2 passing through the point x.

From here, using the properties of angles subtended you know that x/2 equals y. Similar for z.

Hence A is the answer.

Draw a line parallel to the given two lines passing through x.
One part of x is equal to y and other part equal to z.
Hence x =y+z.
A is correct.
