Question

In the following question the measure of two angles are given in each case find the measure of the third angle 30 degree, 80 degree

Answer 1

Answer: answer is 70°

Step-by-step explanation:

angle A + angle B +angle C = 180°

30° + 80° + angle C = 180°

110° + angle C = 180°

angle C = 180° - 110°

angle C = 70°
