Answer:
D. 104 degrees
Step-by-step explanation:
What the information at the top tells us is that triange ABC is an isosceles triangle. In an isosceles triangle the two base angles are congruent, this means that <A=<C. Additionally, because of vertical angles we know that <C is equal to 38. So to find m<B use the expression 180-(2*38). This simplifies to 180-76, which is 104.
