    You can find the answer by taking 180 and subtracting 70 from it. Then divide that answer by two.

    180-70=110.

    110/2=55

    Angle B is 55 degrees. Since Angle B and Angle C are congruent, Angle C is also 55.

    In a triangle, the three interior angles always add to 180°

    m∠B = (180-70) / 2 = 55°
