Question

In the figure, AB and CD are two straight lines intersecting each other at a point. If angle COE=90, then find the values of x, y and z.​

Answer 1

Answer:

value of x,y,z are

x=45°

y=90°

z=90°

Answer 2

x+90+2x = 180  ( linear pair )

3x = 180-90

x= 90/3

x= 30

y = 2x   ( vertically opposite angles )

y = 2(30)

y = 60

y + z = 180 ( linear pair )

    or

2x + z = 180 ( linear pair )

     or

z = 90 + x ( vertically oppasite angles )

z = 90 + 30

z = 120
