△lmn is the result of a reflection of △xyz across the y-axis. which angle in the image corresponds to ∠z in the pre-image?

We have been given that is reflection image of across the y-axis and we have to find which angle from the given image corresponds to .

We know that a refection gives us mirror image of the point or object we are reflecting and line of reflection which in our case is y-axis acts as a mirror. Line of reflection  is equidistant from object or point and its image.

Now let us look at our given image. After looking at our image we see that y-axis is halfway between X and L,Y and M and also Z and N.

We can see that corresponds to .  So our answer is .
