Question

1. if rs = 34.1 and qs = 68, find qr. a 33.9 b 23.9 c 102.1 d 34.1

Explanation:

Step1: Identify the segment - addition postulate

By the segment - addition postulate, if points $Q$, $R$, and $S$ are collinear, then $QS=QR + RS$.

Step2: Rearrange the formula to solve for $QR$

We can rewrite the formula as $QR=QS - RS$.

Step3: Substitute the given values

Given $QS = 68$ and $RS=34.1$, then $QR=68 - 34.1$.
$QR = 33.9$

Answer:

A. 33.9
