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
