Find the unknowm values or angles x and y in each rhombus klmn.

Opposite angles of a rhombus have equal measure.

angle LNM= 23 (interior alternate angles here are angle LNM and angle KLN)

since ML =MN (sides of a rhombus are equal)

angle  LNM = angle MLN = 23
angle LNK = 23 (interior alternate angles LNK and LNM )

angle x= 23 +23 = 46

angle y = 180 - (23+23) 
= 180 - 46 =   134
in short,,

angle x= 46  and angle y = 134

hope it helps you
