Answer 1

Answer:

Hii

What do you mean I don't understand

Answer 2

Answer:

So, are going to be

2b +60+b = 180

3b = 120

b = 120/3

b= 40°

now putting value of b in 2b

2b=2 * 40

=80°

Now'

8a + 2b +60= 180°

8a + 80° + 60° = 180°

8a = 180-140

8a= 40°

a = 5°

putting value in 8a

8a= 8 * 5

= 40

Now,

7c + 8a = 180°

7c + 40° = 180°

c = (180 - 40)/7

c= 140/7

c = 20°

So, a= 5

      b= 40

      c = 20
