Punctele A,B si C sunt coliniare in aceasta ordine.Aflati lungimea segmentului:a)AB,daca AC=20cm,BC=0,12dm

Strike441 [17]

Answer:

The length of the segment AB is 18.8 cm or 1.88 dm

Step-by-step explanation:

<u><em>The question in English is</em></u>

Points A, B and C are collinear in this order. Find the length of the segment: a) AB, if AC = 20 cm, BC = 0.12 dm

we have that

$AC=AB+BC$ ----> by Addition segment postulate

substitute the given values in centimeters

Remember that

$1\ dm=10\ cm$

so

$0.12\ dm=0.12(10)=1.2\ cm$

$20=AB+1.2$

solve for AB

$AB=20-1.2\\AB=18.8\ cm$

Convert to dm

$18.8\ cm=18.8/10=1.88\ dm$

therefore

The length of the segment AB is 18.8 cm or 1.88 dm
