Question

I need help answering this problem pls

Answer 1

Answer: C is 160 and B is 20

This is because they’re vertically perpendicular lines and we know that angles opposite each other equal the same. So the opposite B is 20 so b will also be 20 and to work out c you do 360-40= 320 and then you divide 320/2=
160

Hope this helps

Answer 2

Answer: b = 20 c = 160

Explanation:

the value of a straight angle is 180, so 180-20= 160
