• b = 130°
• c = 50°
• a = 100°

Answer 2

To find the value of c...

60+70+c=180..................... angle sum property of triangle

c=130+c=180

c=50 degree..

To find angle b..

angle c + angle b = 180...............linear pair

50+ angle b=180

b=130....

Now to find angle a....

a+b+30=180

a+130+30=180

a+160=180

a=20..
