Answer:
18.4 cm
Step-by-step explanation:
PO is a radius that is 13 cm. That means that OQ which is also a radius has a measure of 13 cm. Together lines PO, OQ and PQ make a right triangle. PQ is the hypotenuse which we solve for:
c^2= 13^2 + 13^2
c^2= 338
c = 18.4 cm
PS
Line PR can't be 10 cm because using the tangent property it wont mathematically correspond to the other measurements in a right triangle. Try drawing it out and solving for RO to get what I mean.
