Answer:

x = 19.8

Step-by-step explanation:

You want to use tangent, since you are trying to find the opposite side and know the adjacent side to the angle.

tan = opposite/adjacent

31tan = x/33

Multiply both sides by 33

33(31tan) = (33) x/33

33(31tan) = x

Find the tan of 31° using a scientific calculator.

tan 31° is about 0.6

Solve for x

33(0.6) = x

x = 19.83

rounded to the the nearest tenth

x = 19.8

Step-by-step explanation:

\tan(31)  =  \frac{x}{33}  \\ x = 33 \tan(31)  \\ x = 19.82840042791 \\ x = 19.83

Answer:

64°

Step-by-step explanation:

<em>So supplement angles are equal to 180, so first our two angles added together will be 180:</em>

x + x = 180

<em>Now one of these angles is 6 greater than half:</em>

x + (x/2 + 6) = 180

<em>Then we will solve for x:</em>

x + (x/2 + 6) = 180

x + x/2 + 6 = 180

x + x/2 = 174

\frac{3}{2}x = 174

x = 116

<em>Plug it back in:</em>

x + (x/2 + 6) = 180

         /\

     x/2 + 6

   (116)/2 + 6

        64

<em>To check:</em>

116 + 64 = 180 ✓

Will give Brainlest Answer please answer i need help

Answer:

  C.  {-1, 5, 8}

Step-by-step explanation:

Use each of the domain values in the function to see what the corresponding range value is.

  f(-1) = 5 -3(-1) = 8

  f(0) = 5 -3(0) = 5

  f(2) = 5 -3(2) = -1

The range is the set of numbers {-1, 5, 8}.

_____

<em>Additional comment</em>

The values in a set are generally listed lowest to highest. The coefficient of x in the equation for f(x) is negative, meaning the lowest range value will correspond to the highest domain value. If you start by finding f(2) = -1, you immediately eliminate all answer choices except B and C.

Those choices differ only in the middle value, so you can tell which is correct by evaluating f(x) for the middle domain value: f(0) = 5. Only one answer choice has both -1 and 5 in the set.

(There are two answers here: how you work the problem, and how you game a multiple choice question.)
