Find the center and radius of the circle (x+0.2)^2 + (y+0.1)^2 = 0.3

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.

i would say c is the best answer, hope it's right!

good luck! =)
