Step-by-step explanation:

Range is the range of the y-axis.

Although we see that the "line" ends at a specific point, it is neither the highest or lowest y-value.

This is interval notation.

Due to your question, you may be asking for this:

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
