write the ratios for sin x and cos x.

First Option

,  

Step-by-step explanation:

We know that the sine function is defined as:

In the same way the cosine function is defined as:

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  

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

So for angle X:

Finally:

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms
