find x in the given figure. (the vertical chord is a diameter.)

In mathematics, the Pythagorean theorem is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It is expressed as:

c^2 = a^2 + b^2

where c represents the hypotenuse of the right triangle.

We calculate as follows:

16^2 = a^2 + 9^2

a = 5√7

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
