Answer:

x=105,y=70

Step-by-step explanation:

ABC=35 [Isosceles Triangle]

y=35+35=70 [Exterior Angle Property]

BDC=y=70 [Isosceles Triangle]

x=BAC+BDC=35+70=105 [Exterior Angle Property]

Answer:

x = 105 degree

y = 70 degree

Step-by-step explanation:

here, 3 line are equal

let's take the big triangle as ABC

ab = bc

= angle A = angle C

= angle C = 35

= angle A + angle C + angle B = 180

= 35+35+angle B = 180

= angle B = 110 degree

=  y + angle B = 180 (since, linear pair)

= y = 180-110

     = 70 degrre

let's take the smaller trialgle as BCD

= bc = cd

= y = angle D = 70 degree

let angle bcd be z

= y + z + angle D = 180

= z = 180-140

     = 40 degree

= z+x+angle C = 180 (since, straight line)

= x = 180-40+35

     = 180-75

     = 105 degree
