Answer:
X=135° Y=45° Z=135°
Step-by-step explanation:
lets angle AOD be X
angle DOB be Y
angle COB be Z
Now,
angle AOC = angle DOB.......( V.O.A )
angle DOB = 45°
Y = 45°
Now,
angle AOC + angle AOD = 180°........( Linear Pair )
45° + angle AOD = 180°
angle AOD = 180°-45°
angle AOD = 135°
X = 135°
Now,
angle COB = angle AOD........( V.O.A )
angle COB = 135°
Z = 135°
