Question

Find the distance between the origin and the point (10,45,57)

Answer 1

Explanation:

3D space (x, y, z) = (10, 45, 57)

I will use x² + y² = (2D Hyp)² and (2D Hyp)² + z² = (3D Hyp)²

which is just x² + y² + z² = (3D Hyp)²

10² + 45² + 57² = (3D Hyp)²

100 + 2025 + 3249 = 5374 = (3D Hyp)² the destance from the origin

= 73.31 the destance from the origin
