Question

find x and y in the follow8ng diagram
​

Answer 1

in triangle , abc.

angle Abc=65 , Angle Bca= 180-100 (linear pair) =80

( angle sum property )

65+x+ 80=180

65+x=100

x=100-65

x= 35

in triangle ,Adc

angle Acd=100 ,angle CAd =x=35

( angle sum property)

100+35+y=180

35+ y=80

y =80-35

y= 45
