The angle of elevation made from the eyes of the observer to the top of the tower is 45°.

The angle of elevation is the angle formed by the horizontal line of sight and the upward line of sight.

For the given question;

The angle of elevation of the top of the tower to the eyes of the observer is needed.

Thus, for this subtract the height of the observer to the height of tower;

height from the eyes to the tower is 22 - 1.5 = 20.5 m.

Thus, apply the trigonometric rule to calculate the angle;

tan Ф = perpendicular/base

perpendicular is the height of tower from the eyes of boy = 20.5 meter.

base is the distance of the tower from the boy = 20.5 meter.

Put the values;

tan Ф = 20.5/20.5

tan Ф = 1

Ф = 45°.

Thus, the angle of elevation made by the eyes of the observer to the top of the tower is  45°.

Finding the missing angle of the figure, the value of m∠DKL is 110°

Two rays that have a common endpoint and are referred to as the angle's sides and vertices, respectively, form an angle. Two rays can form angles in the plane where they are positioned. Angles are also produced when two planes intersect. These angles are dihedral.

given,

m∠DKL = (21x + 5)°

m∠JKD = (4x + 2)°

and

m∠JKL = 132°

By angle sum property of angles

m∠DKL + m∠JKD =  m∠JKL

substituting the values, we get

(21x + 5)° + (4x + 2)° equals  132°

(21x + 4x + 5 + 2)° =  132°

(25x + 7)°=  132°

(25x)° =  132° - 7°  

x = 125° / 25°

x = 5

now, the value of m∠DKL

m∠DKL = [21 (5) + 5]°

m∠DKL = 105° + 5°

m∠DKL = 110°

Hence the value of m∠DKL is 110°

4 cuboids of dimensions 15, 30, and 15 cm will be needed to form a cube

The volume of the cuboid is l×b×h where l is length, b is breath and h is the height

The volume of given cuboid  = l b h

 = 15× 30 ×15

= 6750 cm3

The volume of a cube is a3 where a is the edge of the cube

The edge of the cube can be 30cm

The function that dose not show y as a function of x.

Y is a function of X, means that a certain variable magnitude or phenomenon Y is determined/caused by another magnitude or phenomenon X, such that the behavior of X will affect that of Y. In logic, a function symbol is a logical symbol that may be applied to an object term to produce another object term.

If a vertical line is drawn such that it touches more than one place, then it is not a function of x.

The principal investment required to get a total amount of $250,000.00 rounded to the nearest cent is $81569.95.

The formula for calculating compound interest is expressed as;

A = P(1 + r/n)^(n*t)

P = A / e^(r*t) compounded continuously

Given the data in the question;

Plug the given values into the equation above and solve for P

P = A / e^(r*t)

P = 250,000 / e^( 0.14 × 8 )

P = 250,000 / e^( 1.12)

P = 250,000 / e^( 1.12)

Karen while putting a fence around the L shaped garden will need about 22.3 ft which is the exact perimeter of this field, with its dimensions as given as 2.1ft by 7.8ft by 5.5ft by2.7ft of the garden.

Any kind of closed path that covers, encircles, or outlines a full one-dimensional length or a two-dimensional shape is called as a perimeter.

The circumference of a circle or an ellipse is referred to as its perimeter. There are varied uses in real life for the perimeter calculations.

For example, in case of a rectangle, there are two equal lengths and two equal widths in a rectangle. Then we must sum up all the lengths of the rectangle’s four sides in order to get its final perimeter.

Since there are like two of each side length, it is easy to accomplish this perimeter by simply adding the length and width and then multiplying the result by two.

In this problem,

Total perimeter = 2.1 + 5.1 + 2.1 + 2.5 + 2.7 + 7.8

= 22.3 ft

Thus, the perimeter has been calculated in total as 22.3 ft.
