Ireally don’t understand 30,60,90 or 45,45,90 triangles, can someone me

Step-by-step explanation:

these two are called special right triangles

one has interior angles with 90° ~ 60° ~ 30° degrees and x, 2x, x√3 side lengths,

the other is called 45° ~ 45° ~ 90° special triangle with side lengths of x, x, and 2x

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
