10. Which one of the following is a polynomial? a) 2x^(1/2) -1
b) x-1/x+1
c) x²+ 3x^(3/2) / x^(1/2)
d) (x² / 2) - (2 / x² )
​

whats the question?

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

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
