Question
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?
The correct answer is:

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°

Use polynomial identities to factor the polynomials or simplify the expressions : 
Polynomial identities are equations that are true for all possible values of the variable. We can perform polynomial multiplication by applying the distributive property to the multiplication of polynomials.
