Question

in a ∆ABC,if A =72° and B=63° find the C​

Answer 1

Answer:

C=180°-72°-63°

C=45°

45° is your Answer

Answer 2

given:

angle A = 72⁰

angle B = 63⁰

therefore, angle(A+B+C) = 180⁰ (sum of angle of a triangle is 180⁰)

so, angle C = 180⁰-(angle B + angle A)

= 180⁰-(72⁰+63⁰)

= 180⁰-135⁰

=45⁰

SO , ANGLE C IS 45⁰
