C. The diagonals of a rhombus are perpendicular.
Answer:
Therefore, x = 23°, ∠LKM = 56° and ∠MKN = 89° .
Step-by-step explanation:
Given that ∠LKN is 145° so we can assume that ∠LKM addes together with ∠MKN will get 145° in terms of x :






Next, we have to substitute x = 23° into the expressions of ∠LKM and ∠MKN :
