Zach tried to solve an equation step by step. \begin{aligned} \dfrac34&=z-\dfrac12 \dfrac34+\dfrac12&=z-\dfrac12+\ dfrac12&\green{\text{Step } 1} \dfrac54&=z&\blue{\text{Ste p } 2} \end{aligned} 4 3 4 3 + 2 1 4 5 =z− 2 1 =z− 2 1 + 2 1 =z Step 1 Step 2 Find Zach's mistake.

Sorry but I can't understand your question because in my phone there's a lot of and & and dfrac

And its nice to meet you

(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
