Question

in triangle ABC angle A =40ⁿ angle B = 70ⁿ then angle C?​

Answer 1

Answer:

Angle A = 40°

Angle B = 70°

Sum of all angles of triangle = 180°

So, Angle C = 180° – ( 70° + 40° )

Angle C = 180° – 110°

Angle C = 70°

so, your answer for Angle C = 70°

Answer 2

Answer:

angle a = A, angle b = B, angle c = C

so,

C-A=40→A=C-40

C-B=20→B=C-20

also,by angle sum property

A+B+C=180

C-40+C-20+C=180

3C=180+60

C=240/3

C=80

so,

A=40

B=60

C=80
