When the speed of an object approaches the speed of light, its length as seen by an observer changes. When the object is stationary relative to an observer, its length is S, and when the same object is moving at speed v relative to the observer, its length is L. The formula above expresses L in terms of S, v, and c, the speed of light. Which of the following gives the speed of the object in terms of the other quantities?

Interior angles are the angles contained within a shape or the region enclosed by two parallel lines transversely intersected.
¶Interior angles form in two ways in geometry. The first occurs within a polygon, and the second occurs when a transversal cuts parallel lines. Angles are classified into various types based on their measurements. Other angles are known as pair angles because they appear in pairs to exhibit a specific property. Interior angles are one example.
¶Sum, S = (n − 2) × 180°
