Answer:

  38.2°

Step-by-step explanation:

The law of sines tells you ...

  sin(x)/15 = sin(27°)/11

  sin(x) = (15/11)sin(27°) . . . . . multiply by 15

  x = arcsin((15/11)sin(27°)) ≈ arcsin(0.619078) ≈ 38.2488°

  x ≈ 38.2°

_____

<em>Additional comment</em>

In "law of sines" problems, you need to identify a side and opposite angle that you know both values of. Then, you need to identify whether you're looking for an angle or a side, and whether its opposite side or angle is known. If two angles are known, you can always figure the third from the sum of angles in a triangle.

Here, we have angle 27° opposite side 11. We are looking for an angle, and we know its opposite side. This lets us use the ratio formula directly. Since the angle is the unknown, it is useful to write the equation with sines on top and sides on the bottom.

The given angle is opposite the shorter of the given sides, so this triangle has two solutions. We assume that we want the solution that is an acute angle  (141.8° is the other solution). That assumption is based on the drawing. Usually, you're cautioned not to take the drawings at face value.

A fish tank has the shape of a rectangular prism. It has a length of 214 m, width of 78 m, and a height of 112 m.
siniylev [52]
To find the volume you have to multiply the length width and height.

Your answer would be 1869504 which is not one of your choices though.

Can you double check you choices?

A meal of a chicken sandwich and some pasta salad had 120 grams of carbohydrates. The pasta salad had 30 grams more than twice t
igomit [66]
C + p = 120.....c = chicken sandwich carbs, p = pasta salad carbs
p = 2c + 30

c + (2c + 30) = 120
3c + 30 = 120
3c = 120 - 30
3c = 90
c = 90/3
c = 30 grams <=== carbs in the chicken sandwich

p = 2c + 30
p = 2(30) + 30
p = 60 + 30
p = 90 grams <=== carbs in the pasta salad
