Question

In figure ab and cd intersect each other at point o. If angle AOC= 45 find x, y, z
.​

Answer 1

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°
