Question

In angle abc, m angle a =65°, m angle b=72° find m angle c



​

Answer 1

As we know that sum of all sides of a triangle is 180 degree, so

a+b+c = 180 degree

65+72+c = 180

137+c = 180

c = 180-137

c = 43

therefore, angle c = 43 degree.

Answer 2

Answer:

43°

Step-by-step explanation:

a+b+c = 180

65+72+c = 180

137+c = 180

c = 180-137

c = 43

m angle c = 43°
