triangle png What is the angle measure of angle B?

Answer:
[tex]m\angle B = 28^{\circ}[/tex]
Step-by-step explanation:
All angles in a triangle must add up to [tex]180^{\circ}[/tex]
We can solve for [tex]\angle B[/tex] using this knowledge
[tex]\angle B + 40 + 112 = 180\\\angle B + 152 = 180\\\boxed{\angle B = 28}[/tex]
That is the answer
