Question

Fill in the reason that justifies the step to solve for x in the diagram Given: QS = 42 X + 3 + 2x = 42 o R A. Substitution PropertyB. Segment Addition Postulate C. Simplify.

Answer 1

`\begin{gathered} QS=42 \\ x+3+2x=42 \end{gathered}`

With the Segment Addition Postulate you have that:

`QS=QR+RS`

As you have that 42 is equal to QS, and 42 is equal to X + 3 + 2, you use
