Answer:
107
Step-by-step explanation:
Since we know that the triangles have the same 3 sides, they are congruent (SSS). We also know that a triangle's angles add up to 180 degrees.
We first need to add 41 and 32 to give us the number we need to subtract from 180.
41+32=73
Now we need to subtract from 180 degrees.
180-73=107
If 107 is the measure of angle D, then according to SSS congruence it is also the measure of angle B.
HTH :)
