How do the values of x and y compare? Explain your reasoning.

Hey, GM   !!!!

Note that we have two right triangles

We have right angles  at  DEA and  DFA

And angle EAD  = angle FAD

And DA  = DA

So....by  Angle-Angle - Side  these triangles are congruent

So triangle DEA  = triangle DFA

So....DE = DF

So....this means that  y  = x
