Given right triangle ABC, what is the value of tan(A)? Five-thirteenths Twelve-thirteenths Twelve-fifths Thirteen-twelfths

WITCHER [35]

Answer:

Twelve-fifths.

Step-by-step explanation:

The diagram is shown below

Given triangle be right angled at $B$ ,

Withe reference to $\angle A$ ,

Its opposite side is $BC=12$ , adjacent side is $AB=5$ and hypotenuse is $AC=13$

We are to find the value of $tan(A)$

We know $tan=\frac{opposite}{adjacent}$

Substituting the above values we get,

$tan(A)= \frac{BC}{AB}=\frac{12}{5}$

So the answer is Twelve-fifths.

The first week of January there are 49 dogs and 28 cats in an animal shelter. Throughout the month the ratio of dogs to cats rem

Rudiy27

Answer:

Step-by-step explanation:

If the ratio of dogs to cats is 49:28, as an actual ratio (fraction), this is

$\frac{d}{c}:\frac{49}{28}$

We can reduce that to make the numbers smaller without changing the ratio. reducing gives us

$\frac{d}{c}:\frac{7}{4}$

We will use that ratio now to set up a proportion that involves a given number of cats and an unknown number of dogs. Keeping dogs on top and cats on bottom,

$\frac{d}{c}:\frac{7}{4}=\frac{x}{20}$

Cross multiply to get

4x = 140 so

x = 35

According to the ratio of dogs to cats, if there are 20 cats, there will be 35 dogs.
