Answer 1

Answer:

X=110 y=70 z=110

Step-by-step explanation:

O and x add up to 180degrees

Answer 2

STEP BY STEP SOLUTION

Here AB and CD intersect at point O and also given angle AOC = 70.

Since Angle BOD AND AOC are opposite angle so angle BOD = AOC = 70 ( OPPOSITE ANGLE IS EQUAL ) So y = 70.

Coming to angle AOD we know that

y + z = 180. ( by properties of a line )

since y = 70 therefore z = 110

Similarly Angle BOC = AOD = 110 ( OPPOSITE ANGLES ARE EQUAL ) therefore x = 110.

To verify :- angle AOC + BOD + AOD + BOC = 360.
