Question

The sum of interior angles of a regular polygon is 2160°.
Find the number of sides of a regular polygon.

Answer 1

Answer:

A number used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1. Example: x is really 1x. Sometimes a letter stands in for the number.
