You can add 46 to 114 first then you can add 3x to x and you should get 160 + 4x

The bearing of the tree from Q is 296.565°

<h3>How to determine the height of the tree?</h3>

The figure that illustrates the bearing and the distance is added as an attachment

The given parameters are:

Base of the tree, b = 50 meters

Angle (x) = 32 degrees

Calculate the height (h) of the tree using:

tan(x) = height/base

So, we have:

tan(32°) = h/50

Make h the subject

h= 50 × tan(32°)

Evaluate

h = 31.24

Hence, the height of the tree is 31.24 meters

<h3>How to determine the distance between Q and the base of the tree?</h3>

The distance (d) between Q and the base of the tree

This is calculated using the following Pythagoras theorem

d = √(100² + 50²)

Evaluate

d = 111.80

Hence, the distance between Q and the base of the tree is 111.80 meters

<h3>How to determine the angle of elevation?</h3>

The angle of elevation (x) using the following tangent trigonometric ratio

tan(x) = h/d

This gives

tan(x) = 31.24/111.80

Evaluate the quotient

tan(x) = 0.2794

Take the arc tan of both sides

x = 15.61

<h3>The bearing of the tree from Q </h3>

This is calculated using:

Angle of bearing = 270 + arctan(50/100)

Evaluate the arc tan

Angle of bearing = 270 + 26.565

Evaluate the sum

Angle of bearing = 296.565

Hence, the bearing of the tree from Q is 296.565 degrees

Sybille makes and sells candles for her Possible Project business. Sybille sells multi-scented candles for $3 each and single-sc
trasher [3.6K]

Answer:

24 multi-scented candles

10 single-scented candles

Step-by-step explanation:

There was no question, so I am going to assume that you want to know how many of each type of candles were sold.

Let m = no. of multi-scented candles

     s = no. of single-scented candles

(1)      m + s = 34             (2)   3m + 2s = 92      

               s = 34 - m              3m + 2(34 - m) = 92

                                              3m + 68 - 2m = 92

                                                  m + 68 = 92

                                                           m = 24

              s = 34 - 24 = 10
