The measure of angle b is 139°
Given :
A figure with angle 41 degrees
From the figure we can see that angle b and angle 41 lies in a straight line
Angles b and 41 are linear pair
Linear pair of angles are supplementary
The sum of linear pair of angles are equal to 180 degrees
So we add these angles and make it equal to 180
[tex]b+41=180\\\b=180-41\\b=139[/tex]
So, the measure of angle b is 139 degrees
