i need help confirming this sorry for the bother and thx

You are wrong.

Here's a graph you can play with:  https://www.desmos.com/calculator/wy7dptwaij

To start with, both angles are set at  38°  so both triangles are congruent (by SAS congruency).

Try changing the slider for  b  to make that angle bigger and see what happens to the length of  YX

And note that the lengths of  WX  and  WZ  stay constant.

*edit*

Here is a new graph with calculation for the lengths of  ZY and  XY  and a slider for the length of  WY  (in the folder):

Try drawing the two triangles together.  They have 2 sides that are the same length.

Both have the same base.   WX=WZ

Both have an adjoining side that is the same length. Shown by the arc.

If i make the angle between them bigger, what happens to the third side?
