The value of x is 18.
Explanation:
Given: AP is tangent to the circle with centre 0. , ,
To find: Find x
Solution:
Consider the attached figure
Here, AP is the tangent, OA, OQ are the radius.
We know that the tangent drawn from an external point is perpendicular to the radius.
So, ΔPAO is a right angled triangle at A.
By using Pythagorean theorem
We have, , . So,
Now,
Hence, the value of x is 18.
