Hey Mate!!

Given,

YA is angle bisector of ∠XYZ

⇒ ∠MYA = ∠NYA

∠ANY = ∠AMY = 90°

In ΔAMY and ΔANY,

∠MYA = ∠NYA                     (Given)

∠ANY = ∠AMY = 90°           (Given)

AY = AY                                (Common)

⇒ ΔAMY ≅ ΔANY                (AAS Congruence)

⇒ AM = AN                           (CPCT)

→ Therefore, AM = AN = 2 cm.

Answer 2

Answer:

angle y a

= 90 degree

• by sector = 45 degree
