x = 13

hope it helps

Answer:

x = 13 units .

Step-by-step explanation:

Given  : A circle with tangent PQ , radius = 5 units , OQ = x .

To find : Find the value of x .

Solution : We have given circle with tangent PQ = 12, radius = 5 units , OQ = x .

The tangent (PQ) to a circle is perpendicular to the radius at the point of tangency ( P).

So, it formed the right triangle PQO.

Now use the Pythagorean Theorem :

(OQ)²  = ( PQ)² + (OP)².

Plug the values PQ = 12, OP =5 units , OQ = x .

(x)²  = ( 12)² + (5)².

(x)²  = 144 + 25 .

(x)²  = 169

By taking the square root .

x = 13 .

Therefore, x = 13 units .
