On a coordinate plane, a triangle has points A prime (negative 2, 10), B prime (negative 6, 4), and (negative 10, 8). What is th
e pre-image of vertex A' if the image shown on the graph was created by a reflection across the line y = x? (10, –2) (–10, 2) (–2, –10) (2, 10)

Since Sin is equal to opposite over hypotenuse
so that's mean Sin(60°) =
#I just rounddown from angle 65° to 60° as the number is not that much different.
and Sin(60°) is equal to
so we got Sin(60°) = =
x =
x ≈ 14
then we can answer C)14.5
the answer D) is not correct for sure because the opposite cannot be longer than hypotenuse in the Right Triangle form.
