Quick trigonometry problem; I'm trying to find the length of x and y for the circle of 22 radius in the picture below, but can't remember how to do it.... Can a kind soul let me know how to?

(Edited to a slightly clearer pic.)

Do your own damn homework!

It's not for homework, it's for 'fun'.

X = 15.56, Y = 7.78

edit:

a^2 + b^2 = 22^2
15.56 15.56 484

X = 15.56
Y= 15.56/2

Is that correct?

Won't x then be 15.56, and y =22 - 15.56 , so y =6.44 ?

No, SlyReaper and others are right - Y isn't 0.5 X
