Answer:
not a polygon
Step-by-step explanation:
The given figure is not a polygon.
What is a polygon?A polygon is a closed plane figure formed by three or more line segments that meet at points called vertices.
Given is figure,
We know that, a polygon is made up of straight lines connected with each other in a close circuit.
Here, in the figure, there is no polygon, but two polygons joined by a vertex.
Hence, we can say that the given figure is not a polygon.

You swam the length of the pond shown below. How far did you swim? If necessary, round your answer to the nearest foot.
Answer:
The answer is 25 feet.
Step-by-step explanation:
You have to apply Pythagoras Theorem :
[tex] {c}^{2} = {15}^{2} + {20}^{2} [/tex]
[tex] {c}^{2} = 625[/tex]
[tex]c = \sqrt{625} [/tex]

La profundidad de una alberca aumenta paulatinamente desde 0.80 metros hasta 3 metros en una longitud de 10 metros cual es el angulo de inclinacion de la alberca
Answer:
El ángulo de inclinación de la alberca es aproximadamente 12.407º.
Step-by-step explanation:
Puesto que conocemos la distancia horizontal ([tex]l[/tex]) y la variación en la profundidad ([tex]h[/tex]) de la alberca, en metros, podemos emplear la siguiente razón trigonométrica para calcular el ángulo de inclinación de la alberca ([tex]\alpha[/tex]), en grados sexagesimales:
[tex]\alpha = \tan^{-1}\left(\frac{h}{l} \right)[/tex] (1)
Si sabemos que [tex]l = 10\,m[/tex] y [tex]h = 2.20\,m[/tex], entonces el ángulo de inclinación de la alberca es:
[tex]\alpha \approx 12.407^{\circ}[/tex]
El ángulo de inclinación de la alberca es aproximadamente 12.407º.

What does AD equal? PICTURE INCLUDED* Triangle congruence and similarity.
Answer:
AD = 7
Step-by-step explanation:
Given that the two triangles are similar by the SSS (side side side) postulate, the triangles share the same ratios when it comes to their sides.
We know the values for lines DB, EB and CB, therefore we can solve for AB, and subtract DB to find AD
We can solve the problem by solving for x:
[tex]\frac{x}{32} =\frac{21}{24}[/tex]
Cross multiply.
[tex]24x = 672[/tex]
Simplify.
[tex]x=28[/tex]
Subtract the value of DB to find AD.
[tex]28-21=7[/tex]
[tex]AD=7[/tex]

Step-by-step explanation:
Martha sells custom painted square canvases. She determined that the amount of tissue paper she'll need to wrap each canvas can be represented by
y= x^2 + 2x + 1, where y is the total square inches of tissue paper and x is the side length of the canvas in inches. Write and solve an equation to determine the side length of the canvas is Martha needs 49 square inches of tissue paper.
Given:
The equation is
[tex]y=x^2+2x+1[/tex]
where y is the total square inches of tissue paper and x is the side length of the canvas in inches.
To find:
The side length of the canvas is Martha needs 49 square inches of tissue paper.
Solution:
We have,
[tex]y=x^2+2x+1[/tex]
Putting y=49, we get
[tex]49=x^2+2x+1[/tex]
[tex]0=x^2+2x+1-49[/tex]
[tex]0=x^2+2x-48[/tex]
Splitting the middle term, we get
[tex]0=x^2+8x-6x-48[/tex]
[tex]0=x(x+8)-6(x+8)[/tex]
[tex]0=(x+8)(x-6)[/tex]
Using zero product property, we get
[tex]x+8=0[/tex] and [tex]x-6=0[/tex]
[tex]x=-8[/tex] and [tex]x=6[/tex]
Side length cannot be negative. So, only possible value of x is 6.
Therefore, Martha needs 6 inches side length of the canvas for 49 square inches of tissue paper.
