Need help if someone can show how this is done plz

8.5

Step-by-step explanation:

use pythagorean theorem to find the other side of the tirange.

fill in what you know:

then solve for c then .

then take the square root of both sides because you just want c.

. then you get that c = 17. now, the radius is half of the diameter. the diameter is the segment ab, which we found to = 17, so if the radius if half the diameter, we divide 17 by 2 and we get 8.5. so, the radius of the circle is 8.5.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

uhhh idk u yolo?
