find x
PT is a tangent to the circle, centre O. OM is perpendicular to the secant RQ. RQ is produced to meet P. Find the value of x

sorry my computer keeps freezing everytime i try to attatch a picture of the question so hopefully thats a good enough description.

From the information given the radius of the circle is greater than 4 and less than or equal to 5.

What does the red print "o" mean?

BTW:
Since x (or PT) is not constained, it appears that

0 is less than x and x is less than tan(90deg)
