2. In Fig. 6.40, X = 62°,
XYZ = 54°. If YO and ZO are the bisectors of
XYZ and
XZY respectively of
XYZ, find
OZY and
YOZ.
We have
X =
,
XYZ =
YO and ZO bisect the XYZ and
XZY
Now, In XYZ, by using the angle sum property
XYZ +
YZX +
ZXY =
So, YZX =
YZX =
and, OYZ =
also,
OZY =
Now, in OYZ
Y +
O +
Z =
[
Y =
and
Z =
]
So, YOZ =
