Answer:
Angle B = 41
Step-by-step explanation:
Step 1: Finding inner C.
A line is 180, so line ACD will be 180.
If one side 113, knowing that line is 180, other part of the line is 180-113 = 67.
Step 2: Finding B.
All angles in a triangle add up to 180.
Given A = 72
We solved for C in step 1, C = 67
A + B + C = 180
72 + B + 67 = 180
B + 139 = 180
B = 180 - 139
B = 41
