Question

In ΔABC , if ∠ A = 70degrees . ∠B = 65degrees ,find the measure of ∠ C .

Answer 1

In triangle ABC

angle A + angle B + angle C =180 degrees

70 + 65 + angle C =180 defgrees

angle C = 180 - 135 degrees

angle C = 45 degrees

Answer 2

Answer:

45 degree explanation :

applying total sum of interior angles property , angle a +angle b + angle c = 180 degree , c= 180- angle a + angle b , angle c = 180 - (65 + 70) , c = 45 degree
