Eis an option btw but i need work provided plz!

PQ is a radius. QS is tangent to the circle. In this scenario (a radius and a tangent passing through the same point of the radius) the two segments are always perpendicular.

This implies that PQS is a right triangle. We know that PQ = 10 because it's a radius.

Also, we have

because PR is a radius and RS is given.

So, we can derive QS using the pythagorean theorem:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

what level of math? also i don't need to be paid if i can you.
