Question

In a ∆ ABC, if angle a=72°andb angle=63° find angle c​

Answer 1

Answer:

A=72

B=63

C=?

Step-by-step explanation:

As, Angle A+B+C=180°

C=180-(72+63)

C=180-135

C=45°

Answer 2

Answer:

In triangle ABC

A + B + C = 180 (Angle sum property of triangle)

72+63+ C = 180

135 + C = 180

C = 180 -135

C = 45
