Angle of depression is 7.7 °  made by the line of sight from the canyon edge to the fire .

The angle of depression is the angle created by the object and the horizontal line as seen from the horizontal line. The distance between two objects is often calculated when the angles and spacing of an object from the ground are known.

let f be the the fire

b is the base of the sheer canyon wall

o be the cliffs of insanity point that is canyon edge

so OB = 7117 Feet

bf = 10 miles = 10 * 5280 = 52800 feet

angle of depression is < xof which is equal to < ofb

let the angle of depression is [tex]\theta[/tex]

now from triangle obf ; it is a right angle triangle , where of = hypotenuse

bf = base , ob = height < ofb = [tex]\theta[/tex]

so , tan [tex]\theta[/tex] = ob/bf = 7117/52800

[tex]\theta[/tex] = [tex]tan^{-1}[/tex] ( 7117/52800) = 7.68 ° = 7.7 °

so angle of depression is 7.7 °

The dimensions of the golf hole found using the indicated variable expressions are as follows;

a. The area of the golf hole is 4·x² + 12·x

b. The perimeter of the golf hole is 8·x + 8

c. The perimeter of the golf hole if the area of the hole is 216 square feet is 56 feet

The perimeter of a geometric figure is found by the length of the boundary of the figure.

a. The area of the gulf hole is found as follows;

The area is a composite figure, which consists of a rectangle of length 3·x and width (x + 4) and a square of length x

Which indicates that the area is A = 3·x × (x + 4) + x×x = 3·x² + 12·x + x²

The area of the hole, A = 3·x² + 12·x + x² = 4·x² + 12·x

The area of the hole is A = 4·x² + 12·x

b. The perimeter of the hole is found as follows;

P = (x + 4) + 3·x + (x + 4) + x + x + x = 8·x + 8

The perimeter of the hole = 8·x + 8

c. The area of the golf hole = 216 square feet, which indicates;

4·x² + 12·x = 216

4·x² + 12·x - 216 = 0

x² + 3·x - 54 = 0

(x + 9)·(x - 6) = 0

x = 6 or x = -9

The perimeter of the golf hole is therefore;

P = 8 × 6 + 8 = 56

Mean is 5.25, Median is 5 and mode is 3.

Given,

In the question:

There are numbers:

3, 4, 5, 7, 6, 8, 8, 5, 3, 6, 4, 5, 3, 3, 7, 7.

To find the mean, median and mode.

Let's Know :

How do you find the mean median and mode?

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.

Now, According to the above statement :

To find Mean:

[tex]\frac{3+4+ 5+ 7+ 6+ 8+ 8+ 5+ 3+ 6+ 4+ 5+ 3+ 3+ 7+ 7}{16}[/tex]

= 84/16 = 5.25

For Median

Arrange in ascending order

3, 3, 3, 3, 4,4, 5,5,5, 6,6, 7, 7, 7, 8,8.

There is an even no. of observations. i.e., 16 numbers.

then, there is no single middle value; the median is then usually defined to be the mean of the two middle values: so the median of

Middle two values is : (5 + 5)/2 = 10/2 = 5

Middle value is 5

For Mode:

The mode is the number that occurs most often in a data set.

Mode is 3 .

Hence, Mean is 5.25, Median is 5 and mode is 3.

In mathematics, a ratio indicates how many times one number contains another.

And when we write quantities in ratio form, we represent ratio with the symbol :

For example: The ratio of A to B is written mathematically as A:B

Another important thing we must note when writing ratios is to always express both quantities in their simplest form.

With the above explanation, we can proceed in answering the question.

The ratio of adults to children which is 400 to 150, can be written mathematically in ratio form as:

Final answer: The ratio of adults to children is:

The original speed of the train was 32 miles per hour.

We have a train. The train travels a distance equal to 288 miles. It is given that if the speed of a train is increased by 4 miles per hour from its original speed, then it takes 1 hour less to cover the distance. We need to find out the original speed of the train.

Let the original speed of the train be denoted by the variable "s". We can write the following equations using the given data:

s = 288/t

(s + 4) = 288/(t - 1)

We will substitute the value of "s" from the first equation into the second equation.

(288/t) + 4 = 288/(t - 1)

(288)×(t - 1) + 4×t×(t - 1) = 288×t

288t - 288 + 4t² - 4t = 288t

4t² - 4t - 288 = 0

t² - t - 72 = 0

t² - 9t + 8t - 72 = 0

t(t - 9) + 8(t - 9) = 0

(t - 9)(t + 8) = 0

The value of time cannot be negative, so the value of "t" is 9. Now, we will substitute this value into the first equation.

s = 288/t

s = 288/9

s = 32

Hence, the original speed of the train is 32 miles per hour.
