Answer 1

48 degrees

84 degrees

Answer 2

What does "isosceles" tell you about angle A and angle B?

Answer 3

@mjdennis the sides are congruent.

Answer 4

That is true, two sides are congruent, and is what the little marks on the sides mean.
What about the two angles that are opposite the sides? Angle A and Angle B. There is something you should know about those two, because the triangle is isosceles.
