Question

in the given figure if ab is parallel to CD then the value of Y is​

Answer 1

Answer:

30°

Step-by-step explanation:

By alternate angles property,

angle APR= angle PRD=100°

So, Angle APR= ANGLE APQ+ ANGLE QPR

or 100=70+y

or y= 100-70

or y= 30°

Hope this helps...

Answer 2

The answer is

Step-by-step explanation:

The ANGLE x=70° (alternate angle)

100°+a=180° (a took for consideration )

a=180°- 100°

a=80°

Angle sum property

x+y+80°=180•

70°+80°+y=180°

y=180 - 150

y=30°
