Consider adding to the incidence axioms another that says "axiom4: every line contains exactly three distinct points." we know that fano's geometry (p. 18) satisfies this set of axioms. explain carefully using only the 4 axioms why there must be at least 7 points and at least 7 lines in order for a geometry to satisfy these 4 axioms.

step-by-step explanation:

(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
