Calcula el valor del lado "c" en el triángulo

Mathematics
1 answer:
ZanzabumX [31]1 year ago
4 0

Usando relaciones en un triángulo rectángulo, se encuentra que el valor del lado c es c = 35.5 unidades.

<h3>¿Cuáles son las relaciones en un triángulo rectángulo?</h3>

Las relaciones en un triángulo rectángulo se dan de la siguiente manera:

  • El seno de un ángulo está dado por la longitud del lado opuesto al ángulo dividida por la longitud de la hipotenusa.
  • El coseno de un ángulo está dado por la longitud del lado adyacente al ángulo dividido por la longitud de la hipotenusa.
  • La tangente de un ángulo está dada por la longitud del lado opuesto al ángulo dividida por la longitud del lado adyacente al ángulo.

El <u>lado opuesto de el ángulo de 26º48' = 26.8º es de 16</u>, de esa forma, puede-se encontrar el lado c de la siguiente manera:

\sin{(26.8^\circ)} = \frac{16}{c}

c = \frac{16}{\sin{(26.8^\circ)}}

c = 35.5º.

Two welders worked a total of 46 h on a project. One welder made $34/h, while the other made $39/h. If the gross earnings of the
Ratling [72]

Answer:

25 and 21 hours respectively

Step-by-step explanation:

Let the number of hours worked by each welder be x and y respectively.

They worked a total of 46 hours. This means :

x + y = 46 hours.......(I)

Now, given their hourly charges, since we have the total amount of money realized, we can make an equation out of it. This means:

34x + 39y = 1669........(ii)

We then solve both simultaneously. From I, x = 46 -y

We can substitute this into ii

34(46 -y) + 39y = 1669

1564 -34y + 39y = 1669

5y = 1669 - 1564

5y = 105

y = 105/5 = 21

x = 46 - y

x = 46 - 21 = 25 hours

The numbers of hours worked by the welders are 25 and 21 respectively

A discount store bought two dozen cameras for $14 each.
____ [38]

Answer:

72.24

Step-by-step explanation:

Price for each camera = 14

Number of camera = 2dozen = 12 x 2 = 24

Total cp = 24 x 14 = 336

~~~~~~~~~~~~~~

Price for each camera=  10.99

Number of cams = 24

Total sp = 10.99 x 24 = 263.76

Loss = 336 - 263.76  = 72.24

4(2p+3)=16<br> solve the equation
Natali5045456 [20]

Final Answer: p = \frac{1}{2}

Steps/Reasons/Explanation:

Question: Solve the equation 4(2p + 3) = 16.

<u>Step 1</u>: Divide both sides by 4.

2p + 3 = \frac{16}{4}

<u>Step 2</u>: Simplify \frac{16}{4} to 4.

2p + 3 = 4

<u>Step 3</u>: Subtract 3 from both sides.

2p = 4 - 3

<u>Step 4</u>: Simplify 4 - 3 to 1.

2p = 1

<u>Step 5</u>: Divide both sides by 2.

p = \frac{1}{2}
