Question

7. Find the value of a,b and c in the below figures​

Answer 1

Answer:

1) a=20, b=130, c=50

Step-by-step explanation:

1)By Angle Sum Property:

60+70+c=180

130+c=180

c=180-130

c=50

By Linear pair Property:

c+b=180

50+b=180

b=180-50

b=130

Now, By Again Angle Sum Property:

a+b+30=180

130+30+a=180

160+a=180

a=180-160

a=20

Hence, this is the solution of this Question
