Answer:

  x = 30

Step-by-step explanation:

In an arithmetic sequence, any given term is the average of the two terms that come before and after. The middle term of this sequence must be ...

  2sin(3x) = (-11 +15)/2

  sin(3x) = 1 . . . . . . . . . . simplify and divide by 2

Then the value of 3x must be 90°, so ...

  x = 90/3 = 30

There is one value of x in the interval [0, 90] that makes this sequence arithmetic: x = 30.

ehidna [41]

Answer:

\frac{y}{x}, the fourth option.

Step-by-step explanation:

Tan A equals the opposite side of the angle A divided by its adjacent side.

The side opposite of A is y and side adjacent to it is x.

So, Tan A equals \frac{y}{x}!
