Answer:

Step-by-step explanation:

We can clearly see the values of sin x at the vertical axis that is y-axis because the function is

y= sin x

[tex]\theta[/tex] will be at x place and the entire will be y

Hence, look at y-axis to get the value of sin x

[tex]sin0^{\circ}=0[/tex]

[tex]sin90^{\circ}=1[/tex]

[tex]sin180^{\circ}=0[/tex]

[tex]sin270^{\circ}=-1[/tex]

[tex]sin360^{\circ}=0[/tex]

Since, The range of sinx is [-1,1] value will fluctuate between this interval only.

By using the given graph, we will see that sin(270°) = -1

How to read a graph?

Here we want to find the value of sin(270°) by using the given graph. First, notice that theta is on the horizontal axis, so we need to find the value:

θ = 270°

Once you found it, you need to see the correspondent y-value of that point. You can see that it moves 2 squares down, which means that for that value we have y = -1.

We will see that for θ = 270°, we have sin(θ = 270°) = -1

So the correct answer is sin(270°) = -1
