1 point
(i) In a triangle ABC if ZA=70°,
ZB=60°, ZC is :
O d. 130°
O O
a. 45°
O b. 50°
O
C. 10°​

Answer 1

Answer:

angle c will be180-(70+60)

angle c=50°

Step-by-step explanation:

hope it may help you

Answer 2

Answer:

ANSWER

Let the angles be a,a+d,a+2d.

Then, a+a+d+a+2d=180

=a+d=60. So angle B=60

⟹C=45

o

So, ∠A=75
