what is the ratio between the radii of circles a and b and what does that ratio represent in terms of nonrigid transformations.

The ratio between the radii of circles A and B is equal to and this ratio represent the scale factor

Step-by-step explanation:

Let

x -----> the radius of circle A

y -----> the radius of circle B

z -----> the ratio between the radii of circles A and B

so

we know that

----> radius of circle A

----> radius of circle B

Find the ratio z

The ratio represent the scale factor of the dilation of radius of circle B to obtain the radius of circle A

Circles A and B are similar, because A translation, followed by a dilation will map one circle onto the other

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
