Find the distance of a point P(x, y) from the origin

Distance from P (x, y) to origin

Points of origin Q (0,0)

By applying distance formula

√(x2 - x1)² + (y2 - y1)²

√(0 - x)² + (0 - y) ²

√x² + y²

Hope this helps you.

answer;

no:

a diagnostic thoracoscopy is always included in the surgical vats

explanation;

vats means video assisted thoracic surgery.

thoracoscopy is an endoscopical procedure completed on the lungs to visualize pleura, lungs and mediastinum using an endoscope

one thing to note is that a surgical thoracoscopy always includes a diagnostic thoracoscopy.

the diagnostic thoracoscopy codes are differentiated by the site and type of procedure performed.
