Answer + ! hassan writes an algebraic expression with four terms. the x-term has a coefficient of 2, and the z-term has a coefficient of -1. the expression has a constant term less than zero. which expression could he have written? a. 2x + z + 5 - 6z^2 b. 2x - z - 5 + 2z^2 c. -2x - z - 5 + 2z^2 d. -2x + z - 5 + 2z^2

(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

b
