hello /wsr/ my semester ended today, can i ask how to find the radius of little circle because our math professor made this as an assignment (when the semester still going) and he said that if some one solve this he/she will exempt the final exam but no one still got the correct answer for this anyone how just what formula or equations thanks.
> will exempt the final exam
nah. you need to take the exam. it'll be easier.

the exam is done m8 , but no one still got the right answer in this figure. the keks
R+r+x=20sqrt(2)/2=10sqrt(2)
R=10
x=rsqrt(2)
r(1+sqrt(2))=10sqrt(2)-10
r=...
this is highschool math

i feel down thanks anyway
You need to draw a line from the center of Small circle (S), to center of Big circle (B). Now make an isosceles triangle with that line we just draw as your hypotenuse, and the legs going to the edge of the box.
Radius of the small circle we will call r.
Your hypotenuse legs will be 10-r, 10-r, and your hypotenuse is 10+r. From there just plug in your triangle equations and you're set.
