Anybody know how to solve this probelm

The answer is 12.

Step-by-step explanation:

The question says QS is a tangent to circle P which means to QS is perpendicular 90° to QS. With provided information, we are able to find the value of QS using Pythogoras' Theorem, a²+b² = c² :

Let c = PR+RS = 5+8 = 13 units,

Let b = PQ = 5 units,

Let a = QS,

13² = 5² + QS²

QS² = 13² - 5²

= 169 - 25

= 144

QS = √144

= 12 units

step-by-step explanation:

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.
