After investigating several quadrilaterals, José formed the conjecture below. The midpoints of the sides of any quadrilateral with two pairs of congruent sides can be connected to form a rectangle. Which of the following is a counterexample to José's conjecture?

(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

can you post the graph?

0.5?

hope your goes well, here's a turkey
