What is the measure, in degrees, of angle b?

The top angle is the same as the bottom angle, since they are vertically opposite angles.

b+20=40

b=40-20

b=20

It is also 20 degrees.

Step-by-step explanation:

angle b+20 degree=40 degree(being vertically oppoite angles)

angle b=40-20

angle b=20

therefore angle b=20 degree.
