Given line LM and point R that lies on line LM, identify the following ratios given that point R lies a/b of the way along line
gavmur [86]

Answer:

See explanation

Step-by-step explanation:

If point R lies \frac{a}{b} of the way along line LM, closer to L than M, then

LR=ax\\ \\LM=bx

Find all needed ratios:

1. \dfrac{LR}{LM}=\dfrac{ax}{bx}=\dfrac{a}{b}

2. By segment addition postulate,

LR+RM=LM\\ \\RM=bx-ax=(b-a)x,

so

\dfrac{RM}{LM}=\dfrac{(b-a)x}{ax}=\dfrac{b-a}{a}

3. RL=LR=ax\\ \\RM=(b-a)x,

then

\dfrac{RL}{RM}=\dfrac{ax}{(b-a)x}=\dfrac{a}{b-a}
