Answer:
sin=0.945
cos=0.325
tan=2.902
Step-by-step explanation:
In a scientific calculator you simply enter "240°" then press cos/sin/tan after the degrees.
center= (0, -9)
r=1
formula for circle= (x-h)^2+(y-k)^2= r^2
(h, k)= center
r= radius
We know that h is 0 since (x-h)^2 is x^2.
We know k= -9 from (y+9)^2
since r^2=1
1) 360
2) 360
here is the answer
Circle A will be similar to circle B when circle A is dilated by a scale factor of 4.
