ANSWER:

x° = 100°

y° = 50°

Step-by-step explanation:

here,

given ABC IS isosceles triangle

where AB = BC

now

so

ANGLE ABC = angle ACB

So

angle ABC = 50°

and

according to TRIANGLES exterior angle law

angle ABC + angle ACB = correspondent exterior angle i.e. angle CAD

so

angle CAD = 50° + 50° = 100°

SO

y° = 50°

& x° = 100°
