In Figure, `/_B A D=78^0,\ /_D C F=x^0a n d\ /_D E F=y^0dot` Find the value of `x\ a n d\ y`

Text Solution

Verified by Experts

For Cyclic quadrilateral `ABCD`(Exterior angle is equal to the interior opposite angles)
`/_BAD=/_FCD=78^0`
`x=78^0`....(i)
` CDEF` is a cyclic quadrilateral
`/_DCF+/_DEF=180^0`(Sum of opposite angle is 180)
`x+y=180^0`
`y=180^0-78^0`
`y=102^0`
