The value of x = 105
The sum of all interior angles of any four-sided figure has 360 degrees
∡F and ∡H are equal
Add all four expressions and set them equal to 360
x + (x + 5) +( x + 5) + (140 - x) = 360
combine like terms
2x + 150 = 360
2x = 210
x = 105
What are interior angles for instance?
Interior angles are those that lie in the interior of a polygon. For instance, a triangle has three interior angles. The other way to outline indoor angles is "angles enclosed in the interior place of two parallel traces while intersected by means of a transversal are known as interior angles".
The exterior is described by means of Merriam-Webster as "being on an outside surface: located at the outside" and "appropriate for use on door surfaces." Defines outdoors as "outer; being on the outer side," and "intended or suitable for outside use."
The system for calculating the scale of an interior perspective is the interior perspective of a polygon = sum of interior angles ÷ wide variety of aspects. The sum of outside angles of a polygon is 360°. The formulation for calculating the size of an outdoors perspective is the outside attitude of a polygon = 360 ÷ wide variety of aspects.
