x +3x = 180

x = 45 = z.

y = 135.

y>z.

The best answer is D.

From the given figure,

X + 3X=180°
then, X= 45°. so from this we can find out that X=Z=45° & Y=3X=3*45°=135°
Hence, Y>Z. Option D

my logic is:

y=3x
and x=z

therefore y = 3z

now since y equals 3 times of z. It means that y > z

Option D
