The angle to the left of < B = 130 - 90 = 40 degrees
Angle to right of <B = 90-51 = 39 degrees
So m < B = 180 - 40 - 39 = 180 - 79 = 101 degrees

I would find the missing angles of the the triangles, using the fact that "all triangles and lines are 180°"
40(angle on the left of B)+39(angle on the right of B)= 79
79 - 180 = 101
∠B is [C] 101°
