Question

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

Answer 1

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.

Answer 2

Answer:

C. $\frac{12}{13}$

Step-by-step explanation:

cos(Z) = cos(C)

cos(C) = 12/13

Because adjacent side over hypotenuse side length.

Therefore, cos(Z) = 12/13.
