What trigonometric ratio could be used to find the missing side? Tangent, Sine, or cosine?

Vera_Pavlovna [14]

Answer:

cosine

Step-by-step explanation:

eliminate each ratio that will not work,

we'll just use Soh Cah Toa, which basically tells us when to use that ratio

Soh stands for sine=opposoite/hypotenuse

a sine ration would be the opposite side, but we are not given the opposite side, we are given the adjacent side, so we can eliminate this

Cah (correct answer)

Cah stands for cosine=adjacent/hypotenuse

x is the adjacent side to 27 degrees and we are given the hypotenuse, so this will work

Finally Toa won't work because

Toa stands for tangent=opposite/adjacent

We can automatically eliminate this because the tangent only uses the two legs, it does not use the hypotenuse

therefore our answer is the cosine ratio

feel free to ask any questions or comments, hope this helps

I don't understand the estimate

BabaBlast [244]

Round the amounts to the nearest whole dollars:

$3.51 rounds to $4

$2.28 rounds to $2

the difference = 4-2 = $2

The actual difference would be between $1 and $2

seis manzanas y 8 peras cuestan $26. Cuánto cuesta xada pera y cada manzana sabiendo que cada manzana cuesta el triple de lo que

vodomira [7]

Con un sistema de ecuaciones, tiene-se que:

Cada pera cuesta $1.
Cada manzana cuesta $3.

--------------

Usando la información dada en el texto, se construye un sistema de ecuaciones para encontrar el precio de cada pera e de cada manzana.
Yo diré que el precio de cada manzana es x y de cada pera es de y.

--------------

La compra de 6 manzanas y 8 peras cuesta $26, lo que significa que una de las ecuaciones es:

$6x + 8y = 26$

Cada manzana cuesta lo triple de cada pera, lo que significa que la outra ecuacione es:

$x = 3y$

--------------

Aplicando esta relacion en la primera ecuación, se encontra el precio de cada pera.

$6x + 8y = 26$

$6(3y) + 8y = 26$

$26y = 26$

$y = \frac{26}{26}$

$y = 1$

Cada pera cuesta $1.

--------------

Para cada manzana:

$x = 3y = 3(1) = 3$

Cada manzana cuesta $3.
