Start with the standard form of a circle, where
is the center of the circle and
is the radius.

Plug in the known values.

This is the circle's equation in standard form.
alright so first ur trying to find adjacent so use cos which is adjacent/hypotenuse you know the angle of c is 90 because it is a right angle
so it gonna be
cos(90)= AC/5
5*cos(90)= AC
5*0=AC
side AC = 0
Answer: 32
