Answer 1

Here is your answer:

In ∆ABC

Since the two sides are equal therefore it is a isosceles triangle


x = 50° ( Angle opp. to equal sides of a ∆ / isosceles triangle)

Now,

50° + x + y = 180° ( Angle sum Property )

50° + 50° + y = 180°

100° + y = 180°

y = 180° - 100°

y = 80°

Answer 2

Two sides are marked as congruent.

:. it is an isosceles triangle.

the angles opposite to congruent side is congruent.

:.x=50

sum of all angles of a triangle is180

:.50+x+y=180

:.50+50+y=180

:.100+y=180

:.y=180-100

y=80.
