I don't know what your looking for, so be more specific, but I'm assuming your solving for x, so that's would be
x = -1
27.30/3 = x/1
then divide both sides by 3
27.30 divided by 3 is 9.1
therefore, the answer is $9.10
If we say that side "a" is the shortest (adjacent), side "b" is the second shortest (opposite), and side "c" is the longest (hypotenuse): then angle A would be 30°, angle B would be 60°, and angle C would be 90°
tan B = b/a
or
a tan B = b
they have 4 as the smallest value in all four options, so we know that
a=44 tan 60° = b
tan 60° = √3
so, 4 tan 60° = 4√3
b=4√3that leaves two options left, so now we find "c":
c^2 = (a^2) + (b^2)
OR



so
a=4, b=4√3, and c=8
Making your answer
B
