If STU is reflected over a horizontal line, what is the length of side S'U'?

What is the original angle? You didn't provide us with enough information. If the angle is reflected, it'll be the same number of units as the original shape.

Hope this helped.

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.

idk
