Question

If AP and AQ are the tangents then what is the radius of the circle?​

Answer 1

Hope it helps!

The radii of the circle is 5cm

Answer 2

$\large\text{5 cm.}$

I think the attachment will help you understand better. I hope it helps.

$\large\underline{\large\underline{\text{Explanation}}}$

The radius meets the tangent perpendicularly. Since three of the angle is right-angled, the last angle $\angle POQ$ is also a right angle.

The shape $\square APOQ$ is certainly a rectangle. Since it has a pair of adjacent sides that are equal in length, it is a square.

So, $\square APOQ$ is a square of a side length of 5 cm.
