What does AD equal? PICTURE INCLUDED* Triangle congruence and similarity.

Answers

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]

A bag contains 42 red, 45 green, 20

pick one candy at random. Find the
probability that it is green or yellow.

Answers

Answer:

65/139 fraction form

0.47 decimal form

Answer:

Step-by-step explanation:

Total sample space , n (s) = 139

no of green candies , n (g) = 45

no. of yellow candies , n (y) = 20

Probability that is green or yellow is

P( g or y) = P(g) + P(y)

= n(g) / n(s) + n (y) / n(s)

= 45 / 139 + 20 / 139

= 65 / 139

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

Answers

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:
