Hey dear here is your answer!!!!!
___________________________
For our convenience let's name the vertices of the triangle:-
A - the top vertice
B - the left vertice
C - the right vertice
We see, ∠ACB + 120° = 180°
Therefore, ∠ACB = 60°
Now, we observe that the triangle is an isosceles triangle because AB = AC.
Therefore, ∠ACB = ∠ABC (equal sides of a triangle subtend equal angles)
So, ∠ABC = 60° = y
Also, x + y = 120
...(Exterior angle of a triangle is the sum of the other two angles of a triangle)
Substitute the value of 'y':-
x + 60° = 120°
x = 60°
So, x and y are 60° each !
