Answer:
80 degrees
Step-by-step explanation:
As shown in the picture the property of an isosceles triangle is that it's two angles are same and one is different.
Angle CAB is 50 degrees hence Angle ABC will also be 50 degrees
We know that the sum of all interior angles of a triangle is equal to 180, hence
180 = 50 + 50 + x
180 - 100 = x
80 = x
