Answer 2

Answer:

Cannot be determined.

Step-by-step explanation:

Since we only know that it's an isosceles triangle we can only determine that ∠A and ∠C will be equal. We cannot identify their magnitude unless it's a right angle triangle in which case ∠B would be 90° and remaining two angles would be 45° each.
