Question

in a traingle ABC , if angle A=72 and angle B=63 find angle C​

Answer 1

Answer:

In triangle ABC

angle A+ angleB+ angle C= 180

72+63+C=180

135+C=180

C=180-135

C= 45

Answer 2

Sum of angles of a triangle = 180 degree

(Angle sum property)

Therefore, Angle A +Angle B+ Angle C=180

i.e 72+63+C=180

135+C=180

C=180-135

= 45 degree
