Riley Clarke · Answer 1

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.

Valencia · Answer 2

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

m∠B = (180-70) / 2 = 55°
