What is the first step in solving the quadratic equation XP – 40 = 0?
taking the square root of both sides of the equation
adding 40 to both sides of the equation
Squaring both sides of the equation
subtracting 40 from both sides of the equation

its definatley   this on your answer choice?

∠cbe and ∠deb are same-side interior angles.

i took the test

(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
