step 1 : Calculating xzy
xyz+zyx+xzy=180°
xzy=180°-54°-62°
xzy=64°
step 2: since O is the bisector so it will divide the angle in two equal part so
oyz=54/2= 27°
ozy=64/2 = 32°
step 3 : calculating yoz
yoz+ozy+ oyz=180°
yoz= 180°-32°-27°
yoz= 121°

Answer
( Given) In △xyz,
∠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=2∠XZY=264o
∠OZY=32o
⇒ Now, In △OZY,∠YOZ+∠OYZ+∠YZO=180o
∠YOZ+27+32=180o
∠YOZ=180−59
∠YOZ=21o
