Answer 2

Answer:

Prove first set of angles is the same:

∠LMN = 50º (Given)

∠PNK = 50º (Given)

⇒ ∠LMN = ∠PNK (Same Angle Values)

⇒ KN // PN

Prove second set of angles is the same:

∠LKM = ∠PKN (Common Angles)

Prove third set of angles is the same:

Since KN // PN and LPK is a straight line

∠MPK = ∠PNK (Same Angle Values)

By property of AAA, the two angles are similar

⇒ LM/PN = MK/NK

⇒ a/x = (b + c)/c

Make x the subject:

a/x = (b + c)/c

x(b + c) = ac

x = ac/(b + c)
