Question

What is the measure of A, in degrees?

Answer 1

B

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
