Answer:
x=44 and y=136
Step-by-step explanation:
Given:AB=AC; Angle A=92
To find: x and y
Proof:-
angle A = angle BAC (Vertically opposite angles)
angle BAC=92
AB=AC (Given)
Angle ABC = angle ACB (as angles opposite to the side are equal)
Angle BAC + Angle ABC + Angle ACB =180(Angle sum property)
92+x+x=180
92+2x=180
2x = 180-92
2x =. 88
x =88/2
x=44
hence, angle ACB = 44
angle ACB + y = 180
44 + y= 180
y = 180-44
y=136
therefore,x = 44 and y = 136
