Question

Write the ratios for sin A and cos A.

Answer 1

Answer: First Option

`sin(A)=(35)/(37)`,
`cos(A)=(12)/(37)`

Explanation:

We know that the sine function is defined as:

`sin(\alpha)=(Opposite)/(Hypotenuse)`

In the same way the cosine function is defined as:

`cos(\alpha)=(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)=(35)/(37)`

`cos(A)=(12)/(37)`
