what means that with angle B2?

if angle A=145 and angle B=9.43, than angle C=180-(145+9.43)=25.57
you got angle C right
so, answer for side and angle B are correct

B_2 = possible angle B for second triangle but in this case there is only one solution = 1 triangle. I label the angles in the second triangle, when there is one as A_2, B_2, and C_2. Same thing with the length sides.

there is only one solution because you are GIVEN one triangle

It doesn't hurt to check for a second triangle just to get practice.
