Answer 1

Answer:

we know that sum of the interior angles of the triangle.l,

so x+xyz+xzy=180°

or, xzy=64°

now we know that zo is the bisector so,

ozy=1/2xzy

ozy =32°

similarly , to us a bisector and so,

oyz + oyz + o =180°

putting their respective values , we get ,

0=180°-32°-27°

hence , o =127°
