Question

Write the ratios for sin A and cos A.

Answer 1

Answer: First Option

$sin(A)=\frac{35}{37}$, $cos(A)=\frac{12}{37}$

Step-by-step explanation:

We know that the sine function is defined as:

$sin(\alpha)=\frac{Opposite}{Hypotenuse}$

In the same way the cosine function is defined as:

$cos(\alpha)=\frac{adjacent}{Hypotenuse}$

Therefore it is fulfilled that:

Opposite: is the length of the side opposite angle

Adjacent: It is the length of the side that contains the angle of 90 ° and angle A

Hypotenuse: It is the length of the side opposite the angle of 90 °

So:

$sin(A)=\frac{35}{37}$

$cos(A)=\frac{12}{37}$
