what is the measure of A, in degrees?

Answer:
B
Step-by-step explanation:
Since AB = AC = 8 then the triangle is isosceles and
∠C = ∠B = 30° ( base angles of an isosceles triangle )
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the base angles from 180, hence
∠A = 180° - (30 + 30)° = 180° - 60° = 120° → B
