Answer 1

Answer:

X =70° AND Y=40°

Step-by-step explanation:

ACB + ACD = 180° {Linear pair}

ACB + 110° = 180° {Given}

ACB= 70°

NOW, ACB = X BECAUSE AB=BC And opposite angles of equal sides are equal. So, x=70°

X + Y + 70°=180° {Angle Sum property of triangle}

Y= 180°-140°

Y= 40°

Answer 2

Answer:

x = 70

y = 40

Step-by-step explanation:

as AB=BC

therefore angle (x=BCA) _ (1)

also BCD is a straight line

therefore angleBCA+angleACD = 180*(where ACD = 110*)

now angleBCA+110*=180*

angleBCA = 180*-110*

angleBCA = 70*_(2)

from (1) and (2)

x=70*

and from the the theorem

( angle sum property of triangle )

we can say that angles(x+y+BCA) = 180*

(70*+y+70*)=180*

(140*+y) = 180*

y = 180*-140*

y= 40*
