EQUATION OF A CIRCLE: (x-h)² + (y-k)² =r²
= (x+1)² + (y-4)² =3
-d would equal 3. just flip its around right?
Answer:
12/13
Step-by-step explanation:
By definition, for a right triangle with an internal angle X
sin X = length of opposite side / length of hypotenuse
in this case,
for angle F, the opposite side = GH and the hypotenuse is HF
hence
sin F = GH / HF = 12/13
