Confused

Since ΔPQR  is congruent to ΔXYZ...............then angle Y  = angle Q

And since ΔPQR is right, angle Q is complementary to angle R

So angle Q  =  90 - 35  =  55°

So angle Y = c°  = 55°

As hectictar so astutely pointed out.....PR should be congruent to  XZ.....however......that means that :

tan Q   = 6 / 12  = 1/2

And

arctan (1/2)  = Q = about 26.56°

But  R + Q  should sum to 90, which they clearly don't

Mmmmmm.....I suppose this means that my original answer is no good ....LOL!!!!!
