all radii in the same circle have the same value. this means that the opposite angles are congruent since the triangle it isosceles. subtract the known angle from 180 (sum of all angles in a triangle always and forever) and then divide the result by 2 since the angles are equal

Yea its an isosceles triangle, so the missing 2 sides are the same. We are learning about this stuff too right now .
