I think it would be conditional, because B depends on A. Of A is false, then B isn’t possible, making it conditional.

We apply the sine rule here:
a/sin(A) = b/sin(B) = c/sin(C)
The side opposite to angle B is AC
The side opposite to angle A is BC
The side opposite to angle C is AB
8.75/sin(37) = 12.35/sin(A)
A = 58.15°
The sum of the three angles is 180°
Angle C = 180 - 58.15 - 37
Angle C = 84.85°
The answer is B
#3 do 26*4
#4 do 3x16
#5 is 3250
#6 do 64x2.5
