Point O is the center of the circle. What is the value of X?
Answer options: 9, 17, 8, 15

Answer:
x = 15
Step-by-step explanation:
OP and PQ intersect at right angles since PQ is tangent to the circle. This implies that OQ will be the hypotenuse in the right angled triangle OPQ.
Applying Pythagoras theorem;
17^2 - 8^2 = x^2
x = 15
