Answer:
x = 71
Step-by-step explanation:
18(x + 1) = -54
to start off, subtract 18 from both sides
18 - 18(x + 1) = -54 - 18
that should give you
x + 1 = 72
(its safe to take out paranthesis from problem by now) now take away 1 from each side
x + (1 - 1) = 72 - 1
10
with reference angle 30°
perpendicular (p) = 5
hypotenuse (h) = x
Now
sin 30° = p / h
1 / 2 = 5 / x
x = 10
Hope it will help :)

B) {(−2, −3), (−3, −2), (2, 3), (3, 2)}
each input of x (-2), (-3), (2), (3) does not have duplicated output value
