∠x=62o
∠xyz=54o
OY is bisector of ∠xyz
OZ is bisector of ∠xzy
To find →∠ozy=?∠(yoz)=?
⇒ As we know, sum of angles of △=180o
∴∠YXZ+∠XYZ+∠XZY=180o
62+54+∠XZY=180
∠XZY=180−116
∠XZY=64o
As OZ is bisector of ∠xzy
∴∠OZY=∠XZY2=64o2
∠OZY=32o
⇒ Now, In △OZY,∠YOZ+∠OYZ+∠YZO=180o
∠YOZ+27+32=180o
∠YOZ=180−59
∠YOZ=21o
