Question

How do I solve it/ answer it?​

Answer 1

The four angles created by the intersecting diagonals are all 90 degrees each.

<LKO, <NKO, <NMO, <LMO = x degrees

the other four angles created by the other diagonals are each 90-x degrees each.

<LKN,<LMN = 2x degrees each

<KLM,<KMN = 180-2x degrees each
