Hope This Helps!!!!!
Assuming the sum of the opposite angle would be 180. We can easily calculate for x and ultimately solve for the angle of B. We do as follows
B + D = 180
3x-12 + x = 180
4x - 12 = 180
4x = 192
x = 48 degrees
Therefore angle B would have a measurement of 132 degrees. Hope this helps.
