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

m∠B = 180 - 30 - 80 = 70°

D: 70

If the measure of angle ACB = 30 and the measure of angle A = 80, the measure of angle B is 70 degrees.

What is the angle sum property?

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

If the measure of angle ACB = 30 and the measure of angle A = 80, To find the measure of angle B

We know that the angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

∠ACB + ∠A + ∠B = 180

30 + 80 + ∠B = 180

∠B = 180 - 110

∠B = 70
