F+V=E+2 solve for E
Please help me

Step-by-step explanation:

Step-by-step explanation:

Solving for a variable is the same as isolating it. In other words, we want to get E alone on one side of the equation. To do that, we can simply subtract 2 from either side, giving us the equation for E

Side note: This equation is one form of an extremely famous result about polyhedra, 3D solids made up of faces (F), vertices (V) and edges (E). Cubes, pyramids, and 12-sided dice (in math words, a dodecahedron) are all examples of these types of shapes, and the equation describes a relationship between the faces (polygons) vertices (points where three faces meet) and edges (lines where two edges meet). The 2 here specifically describes polyhedra that don't have some kind of hole in them. The Platonic solids (the ones in the attached photo) are all described by the relationship

the answer is 62

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
