Answer:

x=8

KN=24

LK is congruent to LM

LN is congruent to NL

Answer: x = 8

             MN = 52

             LK is congruent to LM

             LN is  congruent to NL

ΔKLN and ΔMLN have:

LN ≅ LN

∠K = ∠M = 90°

∠KLN = ∠MLN

=> ΔKLN ≅ ΔMLN

=> KN = MN

=> 7x -4 = 5x + 12

⇔ 2x = 16

⇔ x = 8

=> KN = MN = 7.8 - 4 = 52
