Answer 2

Step-by-step explanation:

a = 180° - 130° ( Linear pair )

a = 50°

Let the angle opposite to ' c ' be ' x '

50° + b + x = 180° ( Angle sum property )

Also let the ' b ' be ' x '

2x = 180° - 50°

x = $\frac{130}{2}$

x = 60°

c = x ( Vertically opposite angles )

c = 60°

So ' b ' and ' c ' will be 60°.
